In practical application, when the durian is packaged by the packaging bag in the technology, as the gas layer is arranged between the inner bag body and the outer bag body, the inner bag body cannot be supported by the outer bag body after being deformed under stress, and the inner bag body is more easily pierced, so that a puncture-resistant durian packaging bag is needed.
Disclosure of utility model
In order to solve the technical problems, the utility model aims to: provides a puncture-proof durian packaging bag.
The utility model adopts the technical scheme that:
The utility model provides a puncture-resistant durian wrapping bag, includes the bag body, the bag body comprises outer bag and inner bag, the outer bag is formed by first inlayer, first middle level and first inlayer complex, the inner bag is formed by second inlayer, second middle level and second inlayer complex, first middle level is formed by PET aluminizer, first PET membrane and first nylon membrane complex, the second middle level is formed by second nylon membrane, second PET membrane and third nylon membrane complex.
As a further improvement of the technical scheme, the first outer layer is made of any one of nylon, BOPP, PET and CCPP.
As a further improvement of the above technical scheme, the materials of the first inner layer, the second outer layer and the second inner layer are PE or CCPP.
The beneficial effects of the utility model are as follows: the first middle layer of the outer bag is formed by compounding the PET aluminized film, the first PET film and the first nylon film, so that the outer bag has better puncture resistance; the inner bag sets up the nylon membrane in second PET membrane both sides, and then makes the inner bag have better resilience performance, when packing into durian, the part of inner bag deformation can be to obtaining the support of outer bag, reduces the deformation degree of inner bag, and then improves the puncture resistance performance of durian wrapping bag.
