Thermal-insulation Bags Manufacturers, Suppliers, Factory

1. Brief Introduction

(1) Product Description

Thermal-insulation bags are multi-layered pouches used by food delivery platforms cold-chain distributors and grocery e-commerce sellers to protect hot meals frozen goods and fresh produce during transit
Reliable performance depends on wall thickness reflective film quality heat-seal integrity and pack-out efficiency rather than unit price alone
Custom sizes printing and packaging design are available to match different brand and use case requirements

(2) Applicable Scenarios and Target Audience

Channel Type	Applicable Scenario	Target Audience
Food Delivery	Hot meal transport on short to medium delivery routes	Restaurants and delivery platforms
Cold Chain and Grocery	Frozen meat and fresh produce shipment	E-commerce grocers and perishables distributors
Meal Kit and Retail	Meal-kit pack-out and retail shelf use	Meal-prep services and retailers
Wholesale and Private Label	Bulk sourcing with custom branding	Distributors and wholesale buyers

(3) Construction and Format

Multi-layer build combines pearl cotton insulating foam and a reflective aluminum film in a composite profile of about 3mm
Standard format of 7.9 x 9.8 inches (20 x 25cm) suits a wide range of daily commercial and retail applications
Integrated self-sealing tape removes the need for extra adhesives and speeds up packing during high-volume fulfillment

(4) Sourcing and Quality Assurance

Confirm the pack-out structure covering units per inner pack inner packs per carton and cartons per pallet before placing a bulk order
Clarify freight terms and transit time by shipping mode since these affect total landed cost beyond the quoted unit price
Three-stage quality control covers raw material intake mid-production stitching and final leak testing on every order
Food-grade certification documents are available together with private labeling and volume-tiered pricing

(5) Leak-proof Performance and Test Data

Samples are checked against dimension and thickness tolerance and inspected for a reflective outer film white inner lining and uniform heat-sealed edges
Self-sealing tape and heat seals are tested by filling the pouch with water sealing it and inverting it for 15 minutes to check for leakage
Insulation test reports should state the ambient testing temperature payload weight and test duration so preservation claims can be verified

2. Basic Specifications

The standard pouch combines pearl cotton insulating foam and a reflective aluminum film into a profile of about 3mm (0.12 inch) measuring 7.9 x 9.8 inches (20 x 25cm), with a tolerance of ±5mm on size and ±0.2mm on thickness. Larger and smaller formats are available on request and each pouch closes with integrated self-sealing tape for faster pack-out. Since pack-out efficiency affects freight cost buyers should confirm units per inner pack inner packs per carton and cartons per pallet before placing a bulk order.

Item	Specification	Remarks
Size (L x W)	7.9 x 9.8 in (20 x 25cm) standard, tolerance ±5mm 6 x 6 in to 11 x 15 in common range for smaller and larger formats	Custom sizes available
Wall Thickness	0.12 in (3mm) standard composite thickness, tolerance ±0.2mm	Thickness customizable; heavier profile improves insulation duration
Film Structure	Reflective silver outer film with white inner lining	Custom colors and printing available
Closure	Integrated self-sealing tape	Removes need for extra adhesive during packing
Pack-out Structure	Units per inner pack, inner packs per carton and cartons per pallet confirmed per order	Packaging quantity adjustable by size and thickness for calculating volumetric weight

3. Material & Safety

The standard build uses three layers: a reflective silver outer film a pearl cotton insulating foam core and a white inner lining that contacts the payload. A lower-cost HDPE or PE liner is available for shorter routes with lighter insulation needs. Standard production uses virgin material with recycled content available on request. All materials are food-grade and BPA-free with FDA LFGB REACH and RoHS documentation available by market. Reusable and recyclable versions are standard while biodegradable or compostable liners are offered as a custom option.

Item	Specification	Remarks
Raw Material	Multi-layer composite of pearl cotton, insulating foam core and reflective aluminum film	Primary construction affecting insulation performance and cost
Alternate Liner	HDPE or PE liner options for lighter-duty applications	Lower-cost option for shorter transit routes
Recycled Content	Standard product uses virgin material; recycled content available on request	Confirm ratio and certification in advance
Eco Attribute	Reusable and washable; recyclable options available	Biodegradable or compostable liner options subject to confirmation
Note: All materials used are food-grade and BPA-free. Relevant compliance documentation such as FDA, LFGB, REACH and RoHS can be provided based on the target market. Biodegradable or compostable options are available on request.

4. Product Physical Properties

Test data is recorded under defined and reproducible conditions rather than open-ended preservation claims. Dimensions and wall thickness are checked against ±5mm and ±0.2mm tolerances. Insulation performance is measured at a fixed ambient temperature of 25°C with a defined payload such as a 500g gel pack over a stated duration so results can be compared across orders. Leak resistance of the self-sealing tape and heat-sealed edges is verified by filling a sealed pouch with water and inverting it for 15 minutes. Buyers should request certified reports stating these exact parameters.

Physical Properties (Factory Lab Test Records). Test data based on the standard 3mm composite construction (pearl cotton, insulating foam core and reflective aluminum film). Actual performance can be adjusted per customer requirements. Data for reference only; certified test reports available upon request.
