Traditional ግራ የሚያጋቡ ሻንጣዎች stretch to plastic film-based. በከረጢቱ ውስጥ የማጠናከሪያ ሚና የከረጢቱን የ PNS ENTICS ቅርፅ ለማቆየት ቁሳቁሶች ይሞላል, የቦርዱ ቅርፅ ያለው መስፋፋት ከበሮ ቅርፅ ያለው ለመከላከል, የቦታ መጫኛ እና መጓጓዣ.

ሆኖም, the traditional baffle bags in the stretch, due to the design is not reasonable, can not guarantee the smooth flow of materials, resulting in some areas of the bag material is not easy to reach, resulting in the inadequate filling. So it is necessary to improve the existing baffle bags, reasonable design of its reinforcement structure.

meshes ግራ የሚያጋቡ ሻንጣዎች, its reinforcement using a grid-like structure, compared with the traditional sheet-like reinforcement to improve the liquidity of the material filling, improve the efficiency of filling, while increasing the effective volume of the bag. Its mesh stretch with two pieces, the middle of a flexible connection structure, making it easier to make tons of bags, and easy to fold and store reduces the weight and volume of the bag.
