Henrik American school purchasing teacher

The lunch bags designed by the Coraggio team for our students are a hit! The insulation keeps food at the right temperature from morning to lunch, as proven by our testing in various conditions. Sturdy zippers and ripstop fabric are ideal for children's everyday use. Parents love that these bags are easy to wipe clean, ensuring hygiene. Thoughtful design and excellent warmth make these bags essential to our school lunch program.

Supakorn Wongthai Mango Pizza Co., Pattaya

Insulated bags designed in collaboration with Coraggio have transformed our delivery service. Reflective materials for nighttime visibility and added sauce compartments significantly improve safety and customer satisfaction. Our pizzas arrive in perfect condition, maintaining the ideal temperature from oven to customer's door. We have reordered, and the positive feedback keeps coming!

Samantha K Procurement Manager, EcoRetail Chain

After an exhaustive search of suppliers in Vietnam and South Korea, we chose Coraggio because of its excellent balance between cost-effectiveness and high-quality insulated bags. What sets them apart is their willingness to source environmentally friendly materials that align with our sustainable ethos. Our customers notice the difference and appreciate the bag's durability and design.

Tyler Australian outdoor store owner

We rigorously tested Coraggio's cooler bags in various outdoor environments and were impressed by their consistent performance. They keep contents cold for over 24 hours, even in direct sunlight. The material's abrasion and puncture resistance are excellent, making it perfect for our adventurous customers. These bags feature antibacterial lining, are easy to clean, and are odor-free. This level of detail in design and functionality makes them a best-seller in our store.

Maria Brand founder

For our artisanal coffee shops in Europe and the Americas, maintaining the temperature and taste of the coffee during delivery is crucial. We were impressed with their custom design process, providing multiple samples until we found the perfect match. Their commitment to using recyclable materials and innovative insulation technology that doesn't affect the taste of their coffee is a significant plus. I was delighted with the detailed feedback on the production process and delivery tracking.

Kenji Marketing Manager

Our outdoor retail chain across Japan requires high-quality cooler bags that can withstand Japan's different climates, from the heat of Okinawa to the cold of Hokkaido. Their professional team designs and delivers samples according to our strict insulation and durability standards, incorporating traditional Japanese totem elements into the design. Customers love the design of this cooler bag, and sales are outstanding.

Olivia Chen Purchasing Manager

We recently ordered 2,000 eco-friendly lunch bags; the collaboration has been fantastic. The custom design incorporated our iconic green and yellow color scheme and logo, which perfectly aligns with the health-focused ethos of our brand. The bags' durability and sustainable materials used have been particularly praised by our customers, with many expressing their satisfaction at the bags' ability to keep meals fresh for hours. Seamless communication and on-time delivery made the entire process a breeze. Since launch, our sales have increased significantly.

Chapter 04

Are the materials and construction food-safe?

Yes, cooler bags are generally designed to be food-safe, primarily if they are intended for storing perishable items. However, confirming this with the manufacturer or checking for relevant certifications is essential. Here’s a breakdown of the materials and construction elements that contribute to food safety:

Interior Lining

PEVA (Polyethylene Vinyl Acetate)

This material is commonly used for the inner lining of cooler bags. It is non-toxic, BPA-free, and food-safe, making it a popular choice for cooler bags. PEVA is also easy to clean and resistant to mold and mildew

TPU (Thermoplastic Polyurethane)

TPU is another high-quality, food-safe material used in the lining of some cooler bags. It is flexible, durable, and resistant to leaks.

Aluminum Foil Linings

Some cooler bags use food-safe aluminum foil linings. These linings help in maintaining the temperature of the contents and are safe for direct contact with food items.

Insulation Materials

EPE Foam (Expanded Polyethylene Foam)

This foam is often used for insulation in cooler bags. It is lightweight, flexible, and generally considered food-safe as it does not directly contact food. However, it is typically sandwiched between the outer and inner layers, so it doesn’t come into direct contact with food.

Closed-Cell Foam

Some higher-end cooler bags use closed-cell foam insulation, which is also food-safe and provides superior insulation.

Outer Material

The outer material, typically made of polyester or nylon, does not come into direct contact with food, so food safety isn’t a concern for the exterior. However, it is important that these materials are durable and easy to clean to maintain overall hygiene.

Food-Safe Certifications

  • Many cooler bags intended for food storage will have certifications like FDA approval (for U.S. markets) or LFGB certification (for European markets). These certifications ensure that the materials used in the cooler bags are safe for storing food and drinks.
  • Always look for information about food safety on the product packaging or description, particularly if you are concerned about storing unpackaged food directly in the bag.

Sealed Seams and Zippers

Cooler bags with sealed seams and leak-resistant zippers help to prevent contamination from external sources, keeping food safe and protected from the outside environment.

Conclusion

Most cooler bags are made with food-safe materials like PEVA, TPU, and food-safe aluminum foil for the interior linings. Although not in direct contact with food, the insulation materials are safe and effective at maintaining cold temperatures. For added assurance, look for certifications such as FDA approval that confirm the bag’s food safety. Always check the manufacturer’s details to verify that the materials are safe for storing food.

Chapter 05

What Are the Different Types of cooler Bags?

Soft-Sided Cooler Bags

These cooler bags are made from fabric materials like polyester or nylon with a flexible, padded design. They are lightweight and easy to carry, making them ideal for picnics, road trips, or daily use. They often feature multiple compartments for added convenience.

Backpack Coolers

These cooler bags are constructed from durable textiles, such as heavy-duty nylon or canvas. They are designed to be worn as backpacks. They provide hands-free convenience and are perfect for outdoor activities like hiking or camping. The textile material offers comfort and flexibility.

Lunch Cooler Bags

Small, portable cooler bags are often made from water-resistant fabric materials like polyester or Oxford cloth. They are perfect for keeping lunch fresh during short trips or for school/work purposes. They are lightweight and typically come with adjustable straps for easy carrying.

Insulated Grocery Bags

Made from non-woven fabric, polyester, or canvas, these cooler bags are designed for grocery shopping, offering lightweight yet effective insulation. They are reusable and environmentally friendly, often used to transport chilled or frozen food items.

Collapsible Cooler Bags

Constructed from flexible textiles like Oxford cloth or polyester, these cooler bags are designed to fold down when unused. They offer convenience in terms of storage, and the textile surface makes them lightweight and easy to clean.

Wine Cooler Bags

Typically made from high-quality textiles such as neoprene, canvas, or polyester, these cooler bags are designed to hold wine bottles. They often have padded interiors and shoulder straps for easy transport to picnics, parties, or dinners.

Beach Cooler Bags

Made from durable, water-resistant textiles like polyester or canvas, these cooler bags are designed for beach outings. They are lightweight, easy to carry, and often contain additional compartments for towels, sunscreen, and personal items.

Each cooler bag has a textile surface, making them lightweight, flexible, and ideal for outdoor and everyday uses.

Chapter 06

What are the dimensions, capacity and loading bear of the cooler bags?

When considering cooler bags, it’s important to understand their dimensions, capacity, and load-bearing capabilities. Here’s a comprehensive overview:

Small/Personal Coolers

  • Dimensions:

Typically 8-12 inches in length, 6-10 inches in width, 6-8 inches in height

  • Capacity:

6-12 cans or 4-9 liters

Key considerations

  • Dimensions are typically given as Length x Width x Height
  • Capacity is often listed in both can count and liters
  •  Load-bearing capacity includes contents and ice/ice packs
  • Actual usable capacity may vary based on ice-to-content ratio
  • Reinforced bottoms and handles can increase load-bearing capacity
  • Balance between size, capacity, and portability is crucial

When Sourcing

  • Specify required dimensions, capacity, and load-bearing needs clearly
  • Consider requesting product specifications and testing certifications
  • Ensure handle and strap strength matches the load-bearing capacity
  • Consider the intended use when selecting size and load-bearing capacity

Remember, these are general ranges. Specific products may vary, so always verify exact specifications with the manufacturer or supplier.

Chapter 07

Are the bags waterproof or water-resistant?

When considering the water protection features of cooler bags, it’s important to distinguish between waterproof and water-resistant properties. Here’s an overview:

Water-Resistant Cooler Bags

  • Most common in the market
  • Repel water to some degree but not completely
  • Can withstand light rain or splashes
  • Made with materials like treated nylon or polyester
  • Suitable for most everyday uses

Waterproof Cooler Bags

  • Less common but offer superior protection
  • Prevent water from entering the bag entirely
  • Often use materials like TPU (Thermoplastic Polyurethane) or PVC coatings
  • May feature watertight zippers or roll-top closures
  • Ideal for activities near water or in very wet conditions

Exterior Material

  • Water-resistant fabrics: Treated nylon, polyester, canvas
  • Waterproof materials: PVC-coated fabrics, TPU-laminated fabrics

Seam Construction

  • Water-resistant: Standard stitching
  • Waterproof: Sealed or welded seams

Closure System

  • Water-resistant: Standard zippers
  • Waterproof: Watertight zippers, roll-top closures

Interior Lining&Testing Standards

  • Both types typically have waterproof linings to contain melted ice
  • Some manufacturers use IPX ratings to indicate water resistance levels

When Sourcing

  1. Clearly specify the required level of water protection
  2. Ask for details on materials and construction methods
  3. Request any water resistance certifications or test results
  4. Consider the intended use and environment for the cooler bags

Remember, even water-resistant bags can leak if submerged or exposed to heavy rain for extended periods. For most general uses, water-resistant cooler bags are sufficient. However, waterproof options may be necessary for activities involving significant water exposure.

Chapter 08

What type of closure system do they use (zipper, Velcro, etc.)?

Cooler bags typically use a variety of closure systems to ensure insulation and prevent leaks. Here’s a breakdown of the common types of closure systems used in cooler bags

Zipper Closure

  • Most Common Type: Zippers are the most widely used closure system for cooler bags. High-quality zippers, especially waterproof or leak-resistant ones, help seal the bag tightly to maintain the temperature inside. Some bags use dual zippers for added convenience and security.
  • Usage: Found in soft-sided coolers, lunch bags, backpack coolers, and collapsible coolers. Zippers are reliable and easy to use but can wear out over time, especially in bags exposed to moisture.

Magnetic Closures

  • Sleek and Convenient: Magnetic closures provide easy access with a sleek design. While not as common as zippers, they are sometimes used in wine cooler bags or compact lunch coolers for a more stylish and convenient option.
  • Usage: Usually in smaller or more premium cooler bags where style and ease of use are prioritized.

Velcro Closure

  • Easy Access: Velcro closures provide a quick and easy way to access the bag’s contents, but they may not be as effective at sealing in cold air compared to zippers. Velcro closures are typically used in smaller bags or sections of larger cooler bags for fast access.
  • Usage: Sometimes used in lunch cooler bags or insulated grocery bags for simple access to a single compartment.

Buckles and Clips

  • Heavy-Duty Security: Some heavy-duty or outdoor-focused cooler bags may feature buckles or plastic clips, often in combination with zippers. These provide additional security to keep the bag tightly closed during transport.
  • Usage: Commonly used in backpack coolers, camping coolers, or roll-top designs.

Roll-Top Closure

  • Waterproof Design: Roll-top closures involve rolling the top of the bag down several times and securing it with a buckle or clip. This closure style is often used for cooler bags that need to be more water-resistant or waterproof, as it provides an airtight seal.
  • Usage: Mostly seen in beach or outdoor coolers where waterproofing is a priority.

Drawstring Closure

  • Simple and Lightweight: Drawstring closures offer a simple and lightweight way to close smaller bags, but they are not as effective at sealing in cold temperatures. These closures are less common in insulated bags meant for longer cooling durations.
  • Usage: Used primarily in insulated grocery bags or smaller lightweight coolers.

Conclusion

  • Zipper closures are the most common and provide the best seal for maintaining temperature and preventing leaks.
  • Velcro, buckles, and clips are used for convenience or added security.
  • Magnetic, drawstring, and roll-top closures offer specific benefits based on the design and intended use of the cooler bag.

Chapter 09

Are there any additional features like multiple compartments or outer pockets?

Yes, many cooler bags come with additional features like multiple compartments and outer pockets, depending on the model and design. Here’s a breakdown of the most common features

Multiple Compartments

  • Separate Storage Areas: Some cooler bags, especially larger ones, come with multiple insulated compartments, allowing you to store cold items separately from dry goods or other products. This is especially useful for organizing different types of food and drinks.
  • Usage: Found in backpack coolers, picnic cooler bags, and soft-sided cooler bags. It’s great for separating items like snacks, beverages, and ice packs without them touching directly.

Outer Pockets

  • Extra Storage: Many cooler bags have outer pockets made from fabric or mesh. These are used to store non-perishable items, such as napkins, utensils, or personal items like phones and keys. Outer pockets provide easy access without needing to open the main cooler compartment.
  • Usage: Common in soft-sided coolers, backpack coolers, and lunch bags. Outer pockets help keep small items organized and easily accessible

Mesh Side Pockets

  • Flexible Storage: Mesh side pockets are often used for holding water bottles, cans, or other quick-access items. They are not insulated but provide a convenient place to store things you need to grab quickly.
  • Usage: Seen in backpack coolers and beach cooler bags. These pockets can also be used to store items like sunscreen or snacks.

Bottle or Cup Holders

  • Convenient Beverage Holders: Some cooler bags include built-in holders for bottles or cups, making them ideal for outdoor activities or parties. These holders are usually located on the sides of the bag.
  • Usage: Found in picnic coolers or beach coolers, especially those designed for social gatherings.

Interior Mesh Pockets

  • For Organization: Interior mesh pockets are used to store smaller items inside the cooler bag, such as ice packs, utensils, or condiments, keeping them separated from the main contents.
  • Usage: Common in soft-sided cooler bags or lunch bags. These help to organize items that don’t need to be in direct contact with ice or cold food.

Insulated Lid Pockets

  • Additional Cold Storage: Some cooler bags feature insulated pockets on the lid, offering extra space for items that need to stay cool but don’t require as much insulation as the main compartment.
  • Usage: Seen in higher-end coolers, these pockets can be used for small items like sandwiches or snacks.

Bungee Cords or Straps on Top

  • Extra Carrying Capacity: Some cooler bags feature bungee cords or adjustable straps on the top, allowing you to carry extra gear or clothing. These are especially useful for outdoor adventures where you might need to bring extra items.
  • Usage: Found in beach coolers, backpack coolers, and some collapsible cooler bags.

Removable Liners

  • Easy Cleaning: Some cooler bags come with removable liners that can be taken out for easy cleaning. This feature is particularly useful if spills or leaks occur inside the bag.
  • Usage: Found in higher-quality soft-sided coolers and lunch coolers.

Shoulder Straps and Handles

  • Carrying Convenience: Many cooler bags come with adjustable shoulder straps for hands-free carrying, in addition to regular handles. Some backpack coolers also have padded shoulder straps for comfort.
  • Usage: Found in almost all types of cooler bags, from lunch bags to large cooler backpacks.

Waterproof or Water-Resistant Base

  • Protects Against Moisture: Some cooler bags feature a reinforced, waterproof, or water-resistant base to protect the bag when placed on wet or damp surfaces, such as grass or sand.
  • Usage: Common in beach coolers, picnic coolers, and camping coolers.

Chapter 10

How long do cooler bags stay cold and warm?

The duration that cooler bags can stay cold or warm depends on several factors, including the type of bag, insulation quality, external conditions, and whether ice packs or other cooling and warming elements are used. Here’s a general guide:

Cold Retention

Soft-Sided Cooler Bags

  • Cold Duration: Typically, these bags can keep items cold for 4 to 12 hours**, depending on the insulation quality and how often the bag is opened. Using ice packs or ice blocks can extend the cooling time.
  • Factors: Opening the bag frequently or placing it in direct sunlight can reduce the cooling duration. Using higher-quality insulation like closed-cell foam may help the bag stay cold longer.

Backpack Coolers

  • Cold Duration: These bags, with proper insulation and ice packs, can stay cold for about 6 to 12 hours. Some high-end models may keep items cold for up to **24 hours if packed properly.
  • Factors: The insulation quality and the amount of ice or ice packs used can affect how long the contents stay cold.

Lunch Cooler Bags

  • Cold Duration: Lunch cooler bags generally keep food cold for around 3 to 6 hours without ice packs, and up to 8 hours with ice packs.
  • Factors: Because they are small, they lose cold faster than larger cooler bags, especially if opened frequently.

Insulated Grocery Bags

  • Cold Duration: These bags can keep groceries cold for around 2 to 4 hours. If using ice packs, they may keep items cold for up to 6 hours.
  • Factors: They are designed for short-term use, so cold retention is limited compared to more specialized cooler bags.

Collapsible Cooler Bags

  • Cold Duration: These bags typically keep items cold for 4 to 8 hours. Collapsible bags tend to have less insulation compared to rigid or premium cooler bags.
  • Factors: Using ice packs can improve cold retention, but they are more suited for short trips.

Wine Cooler Bags

  • Cold Duration: Wine cooler bags usually keep bottles chilled for around 3 to 6 hours without ice packs. If ice packs or cooling sleeves are used, this can extend to around 8 hours.
  • Factors: The cooling duration is shorter since these bags are typically smaller and opened more frequently.

Beach Cooler Bags

  • Cold Duration: Typically 6 to 12 hours, depending on the bag’s insulation and whether ice packs are used.
  • Sun exposure and frequent opening can reduce the cooling time, so it’s important to pack the bag carefully and keep it in the shade when possible.

Warm Retention

Soft-Sided and Backpack Coolers

  • Warm Duration: These cooler bags can keep food warm for around 2 to 4 hours. While the insulation works both ways, these bags are generally designed more for cold retention than warmth.
  • Factors: Using a heat source, such as a warming pack, can extend the warmth, but frequently opening the bag will reduce its heat retention.

Lunch Cooler Bags

  • Warm Duration: These bags can keep food warm for approximately 2 to 3 hours, which is typically sufficient for short trips or packed meals.
  • Factors: Placing hot food in the bag and minimizing air exposure will help maintain warmth for a longer period.

Wine Cooler Bags

  • Warm Duration: Although not primarily designed for warm retention, wine cooler bags can keep drinks at a stable temperature for about 1 to 2 hours if needed.
  • Factors: These bags are more suited for temperature stability rather than warmth, so additional insulation may be required if used for warm drinks.

Insulated Grocery Bags

  • Warm Duration: Insulated grocery bags can keep hot food warm for around 1 to 3 hours, depending on the quality of the insulation.
  • Factors: While more commonly used for cold items, they can effectively keep food warm

Conclusion

  • Cold retention in cooler bags can range from 4 to 24 hours, depending on the size, insulation quality, and the use of ice packs.
  • Warm retention typically lasts between 2 to 4 hours, as these bags are primarily designed for cold retention. Additional cooling or warming elements (like ice packs or heat packs) can significantly extend these durations. Always consider the external environment and how often the bag is opened, as both factors will affect temperature retention.
