Information

Bone bag is also called sealed bag. There are two hard plastic strips at the mouth of the bag. Two plastic strips can be combined to achieve a sealing effect. As we all know, the sealing of the bone bag is very tight, and it is widely used in clothing, food, medicine, tea, medicine and electronics industries. There are also many materials for the bone bag, and the common ones are PP, OPP, PE, PVC and PO. So what are the characteristics of these five materials?


In recent years, PVC products can be seen everywhere in our lives. Its main feature is good tension and not easy to break. PP bone bag is harder and has high transparency. The disadvantage is that the tension is insufficient and it is not easy to break. OPP bone bags are relatively brittle and have high transparency. It has the same problems as the PP material, there is not enough tension and breakage, and the printing is easy to fade. PE bone bag has soft material and low transparency, but it has good stretching effect and will not break. PE is not soft enough, usually, plastic wrap made of PE is very thin, cheap and easy to make in bone bags. This kind of packaging is not demanding and the production process is simple. The PVC material sticky bag becomes transparent, divided into ordinary materials and abrasives. The PO material of the bone bag is brittle, and its transparency and tensile strength are somewhat unsatisfactory compared with other materials.


Ordinary bone bag is usually made of PE material. PE has the characteristics of flexibility, good toughness, moderate transparency, environmental protection, acid and alkali resistance, and can be used in industrial and agricultural bags. Such as fertilizer bags, hardware accessories packaging bags, clothing sealing bags, bone bags and other forms. There are more material choices for sticky bone bags and zipper bone bags. These two types of bags are used in high-tech fields. For example: bone bags for food packaging, aluminum foil food bone bags, stationery zipper bone bags, clothing zipper bags, etc. The materials used are PE, PP, PVC and composite plastics.
