Our insulated bag benefits
Traditional market products include incubators, foam products, and disposable plastic bags. Our customised insulated bags have been significantly improved in terms of weight, practicality, and commercial adaptability, making them more suited for organisations with large-scale procurement requirements and long-term collaboration with us. The product performs better overall and covers a wider range of scenarios.
The key benefits are as follows:
We provide a comprehensive selection of insulated bags, all of which can be customised in bulk based on their purpose and structure:
- Cold chain insulated bags have a strengthened insulated layer and are used to transport fresh fruits and vegetables, meat, seafood, frozen products, pharmaceuticals, and vaccinations over long distances. Can be used with either ice packs or dry ice.
- Catering insulation bag: leak-proof insulation, excellent for takeaway, beverages, coffee, baked goods and hot meals, and foldable for storage.
- Outdoor camping insulating pack is tiny, lightweight, and easy to store, making it ideal for outdoor activities like picnics and camping.
- Supermarket retail thermal bag: simple and practical, appropriate for supermarkets, convenience stores, and fresh food stores, making it easy for consumers to transport both fresh and cooked food.
Classified according to structural style
- Handheld insulated bag: Classic design, strong handle, ideal for daily short-distance hauling.
- Shoulder insulated bag with ergonomic double shoulder strap design, ideal for heavy-duty goods and outdoor use.
- Wardrobe-style insulated bag: outstanding sealing effect, high-quality KBF hardware, and waterproof insulated bag design, ideal for high-demand cold chain scenarios.
We use only approved raw ingredients to ensure consistent quality and performance
The main structural layers are as follows:
Outer protective layer
600D Oxford cloth is tear-resistant, waterproof, and wear-resistant, with a long service life. It is ideal for high-strength and high-frequency use. 210D Oxford cloth is easy to fold, structurally sturdy, and ideal for short-distance and retail series. PVC coated cloth is very waterproof, easy to clean, and resistant to low temperatures, making it ideal for frozen products and dry conditions. Non-woven cloth is a low-cost, ecologically beneficial option for temporary and low-frequency use.
Intermediate insulation layer (core)
EPE pearl cotton is heat-insulating, cushioning, non-irritating, and odourless. Aluminium foil cotton: Reflects cold and hot radiation, extending insulation period; ideal for long-distance cold chains. EVA foam cotton is a professional insulation material that performs consistently in both high and low temperature conditions, making it ideal for fragile products.
Inner contact layer
Food grade aluminium foil is odourless, oil and water resistant, and meets catering and fresh food safety standards. Food-grade PE film is soft, waterproof, and resistant to low temperatures, making it perfect for frozen foods and beverages. Fabric lining: strong and robust, ideal for heavy-duty cold chains and outdoor environments, with excellent sealing performance.
Applications of Insulated Bags Across Industries

How to choose an appropriate insulated bag
Clear usage scenario:
choose thicker versions for long-distance cold chain; choose compact delivery choices; and select a compact backpack for outdoor use.
Confirm temperature and duration: For short-term usage (≤ 4 hours), use standard pearl cotton + aluminium foil; for long-term use (≥ 8 hours), pick thick aluminium foil cotton or EVA cotton.
Match product size:
measure length, width, and height, and leave 5-10 centimetres of buffer space to avoid compression; custom sizes are available for irregular objects.
Prioritise material compliance:
the interior of food grade insulated bags is utilised for food contact; a wear-resistant outer layer is chosen for industrial use; and export products must meet international safety and environmental standards.
Combining order volume and budget:
choose basic models for small batches and low-frequency use; for large-scale and high-frequency use, go with thick and robust models for long-term cost-effectiveness.
Our insulated bag is more durable because to its standardised structure
- The major components include an outer protective layer that is wear-resistant, waterproof, and tear-resistant, determining the product's durability and service life.
- The intermediate insulation layer is the primary functional layer that prevents heat transfer and keeps temperatures stable. Inner contact layer: in direct contact with things, waterproof, hygienic, and leak-proof. Zipper (strong sealing), Velcro (easy opening and shutting), and snap fastener (tight closure).
- Carrying system: strengthened handheld, adjustable shoulder straps, and hanging loops for convenient use. Reinforcement components include edging, corner guards, lining supports, anti-deformation, and prolonged service life. Customised accessories include a logo printing area, ice pack attaching tape, a transparent window, and a waterproof insulated bag blocking plate, among others.
Product Maintenance and Precautions
fold
Fold gently when idle to minimise squeezing or twisting and to protect the insulation layer.
load-bearing
Do not exceed the load-bearing limit specified on the label to avoid breaking the handle or damaging the insulation layer.
check
Before each usage, check the zipper, shoulder strap and stitching for damage and repair it as soon as possible.
Precautions for Use
Do not exceed the intended temperature range, as this will impair the insulation effect. To avoid frostbite or contamination, keep ice packs or dry ice away from each other inside the bag.

FAQ
Which type of insulated bag is ideal for long-distance cold chain transportation?
We suggest using a zip with an outside layer of 600D Oxford cloth, a thick aluminium foil cotton insulation layer, and a food grade aluminium foil inside layer (thickness 8mm). When used with ice packs, it can keep a consistent temperature for 8-12 hours.
How do I find a lightweight, heat-resistant insulated bag?
We recommend Velcro made of 210D Oxford cloth, EPE pearl cotton, and food grade PE film for hand withdrawal since it is lightweight and foldable.
Can we create insulated bags for alien products?
Okay. We give product size, shape drawings, and special requirements, and can customise to your specifications within a 5-10 centimetre buffer space.
What is the minimum order quantity? Does it support small batch customisation?
The regular minimum order quantity is 500 pieces, while the minimum order number for customised products is 1000 pieces. Support small batch trial orders (minimum of 100), with somewhat higher unit pricing.
How can I confirm that the insulating effect meets the requirements?
We can give free test samples as well as data on temperature control duration in simulated conditions.
Does the insulation bag's material meet international safety and environmental standards?
Yes. All materials meet EU REACH, ROHS, and US FDA regulations, and formal certificates and testing results can be provided.
Is the liner food-grade? Can I come into immediate contact with the food?
Of course. Food grade insulating bags are produced from food-grade aluminium foil or PE film, which is safe, non-toxic, odourless, and meets food packaging regulations.
What is the service life of your insulating bags?
Frequent use can last one to two years, whereas low frequency use can last three to five years. Not readily worn or destroyed under typical conditions.
What technology is utilised to create the logo? Will it fade?
We provide silk screen printing, heat transfer printing, and embroidery services. It is solid and does not fade with regular use.
What is the waterproofing effect?
Our product is IPX4 waterproof, with sealed car cables and waterproof insulation bag stoppers to effectively prevent rain and leaking.
Can thermal insulation packs be washed using water?
The surface layer can be cleaned with a cloth, while the inside layer can be rinsed. To prevent damage to the insulation layer, do not machine wash or soak for an extended period of time.
How do I avoid mould during long-term storage?
After entirely drying and neatly folding, store it in a drawer or cabinet with desiccants to prevent moisture.
Can thermal insulation bags hold hot beverages?
Yes, food grade insulated bags can keep hot drinks, but be mindful of the storage time.
Can damaged insulation bags be repaired?
Small cracks can be fixed with thread or glue, but if the insulation layer is substantially damaged, it is best to replace it.
How long does it take to prepare a sample?
Conventional samples take 3-5 days to complete; complex customised samples require 7 days.
How long is the delivery time for bulk goods?
Regular orders typically take 7-15 days and can be altered based on order size and timing.
Does your factory support exports?
