1. Heating and cooling:

　　 heat preservation is the most basic function of take-out bags. Special packaging bags with short-term heat preservation effect can keep heat preservation/heat preservation. The product heat preservation layer uses pearl cotton, aluminum foil, and tin foil to provide good heat preservation effect.

　　2, durability:

　　 must have superior impact resistance, not easily broken or damaged under heavy pressure or collision.

　　3, seal:

　　 This is another consideration when choosing a takeaway bag. Although different brands of products have different sealing methods, excellent sealing performance is necessary for the continuous preservation of takeaway food.

　　5, multiple sizes, diversity:

　　 Take-out bags can be designed in various sizes according to delivery needs, and used with reusable ice packs. The ice packs can retain heat (the ice pack can be frozen to a minimum of -190 degrees, and can be heated to a maximum of 200 degrees), and can be cut at will.

　　6. Environmental protection:

　　 Food-grade environmentally friendly materials, non-toxic, anti-ultraviolet, not easy to change color
