Keep warm and cool:
Thermal insulation is the most basic function of thermal insulation package. It is a special bag with short-term thermal insulation effect. It can keep cold/heat. The product thermal insulation layer is Pearl cotton+aluminum foil tinfoil, which can provide good thermal insulation effect.
To have superior impact resistance, heavy pressure or impact is not easy to crack, will not leave scratches.
This is the first consideration in choosing insulation package. Although different brands of products have different sealing methods, excellent sealing is a necessary condition for durable preservation of food in memory.
The international standard for sealing measurement is based on the permeability test. The permeability of high-quality thermal insulation packages is 200 times lower than that of similar products, which can keep things fresh for a longer time.
