Most grain packaging bags are very soft packaging bags. Such bags cannot be used to pack thorns or hard objects, otherwise the bags will break and the products cannot be packaged.
As aquatic products with thorns, they cannot be packaged in such bags. If they need to be packaged, a hard plastic bag is used. The wall of this bag is very thick and cannot be pierced by thorns. It is mostly used for packaging frozen aquatic products.
In addition, the hard bags in plastic packaging bags can also be used to pack most of the seasonings, because the seasonings are also angular.
The hard plastic bags in plastic packaging bags meet the hardness requirements, but this kind of packaging bag has poor toughness and will break once torn, and is not crack-resistant.
