خصائص المواد المختلفة لأكياس الحاويات البلاستيكية?

إن استخدام FIBC في حياتنا أمر شائع جدًا. We use plastic أكياس الحاويات according to the production of different materials，
يمكن تقسيمها إلى نوعين. واحد هو مادة البولي ايثيلين, والآخر هو مادة PP. To know these two materials have good low-temperature resistance and good chemical stability.
After that made of plastic containers, which of these two materials better performance?

ال كيس حاوية made of PE is easy to aging and requires careful maintenance; PP is a semi-crystalline material; it is harder than PE and has a higher melting point. When the homopolymer type of PP temperature is higher than 0℃, the plastic كيس حاوية is very brittle. هكذا, many commercial PP material is a random copolymer having 1-4% ethylene or higher ethylene content ratio.Copolymer.PP type polymer type has low heat distortion temperature, low transparency, low gloss, and low rigidity, but has a stronger impact strength. With the increase of ethylene content, the strength of PP increases. Bulk bags made of PP material are more expensive.
