The difference between thermal insulation bags and cold storage bags
1. The functions of thermal insulation bags and cold storage bags are different.
2. Insulation bags and cold insulation bags are made of different materials.
The difference between thermal insulation bags and cold storage bags:
The thermal insulation package, also known as a passive refrigerator, is a package with high heat insulation and a constant temperature effect (with the effect of warm in winter and cool in summer), which can keep cold, keep warm and keep fresh.
Cold packs are ice packs that keep cold.
The inner layer of the thermal insulation bag is made of pearl cotton covered with an aluminum foil reflective thermal insulation layer, which provides a good thermal insulation effect.
The contents of the cold-insulation bag are cold-preserving agents, and the outer bag is made of environmentally friendly plastic bags.
Specifications of insulation bags:
The market price of large bags is about 200 yuan, size: outer size: 63*48*36cm, actual available inner size: 57*42*36cm. The large bag can hold 30-50 large lunch boxes and can be stacked together as a heat preservation turnover box, which is much better than the commonly used iron heat preservation box.
The main dimensions are:
1. Outer size: 42*25*23cm Inner size: 40*23*23cm
2. Outer size: 45*25*23cm Inner size: 43*23*23cm
3. Outer size: 40*32*30cm Inner size: 38*30*30cm
In addition to the large thermal insulation bag and the medium thermal insulation bag, there is also a type of thermal insulation bag called Western food, which is specially used in Western restaurants.

Outer material: The mesh cloth is laminated with PVC on both sides, waterproof and oil-proof, super tensile strength, friction resistance, and strong wrinkle resistance.
Inner material: aluminum foil laminated with non-woven fabric or laminated with 2mm pearl cotton and reinforced with PVC, with 8mm ultra-dense thermal insulation cotton in the middle.
Support material: hard plastic board at the bottom; 2cm high-density super-hard extruded plastic board around and at the bottom.
