Abstract
The utility model relates to an ash-flying prevention plastic woven cement packaging bag, which belongs to the field of packages. The opening of the packaging bag is divided into three sections which are a left folding composite film (1), a middle folding composite film (2) and a right folding composite film (3) in sequence. The left folding composite film (1) and the middle folding composite film (2) have the same height, and the right folding composite film (3) is higher than the left folding composite film (1). The folding composite films of the opening of the packaging bag are all folded twice, and the right folding composite films is designed higher than the other folding composite films, so as to form a folding structure with a wrap angle and effectively solve the ash-flying problem. Meanwhile, the lining pate is eliminated, so as to save cost.
Description
Technical field
The utility model belongs to packaging group, and particularly a kind of blowout prevention ash is moulded the volume cement package bags.
Background technology
The method that tradition solves cement packing spray ash is at the packaging bag internal lining paper, but makes moist or the internal lining paper fracture at cement, sneaks into cement, affects the quality of cement, and is unfavorable for recycling, causes waste, and lining paper has also increased cost.Therefore can utilize the multiple film of bag of cement itself to seal by changing the structure of cement packing sack, reach the blowout prevention ash and saving cost purpose seems very necessary.
Summary of the invention
The purpose of this utility model is to provide a kind of blowout prevention ash that utilizes the multiple film of bag of cement itself to seal to mould the volume cement package bags.
The utility model is achieved in that cement package bags comprises packaging bag body and packing sack, the packing sack is divided into three sections, be followed successively by the folding multiple film in left side, middle folding multiple film, the folding multiple film in right side, the folding multiple film in left side and middle folding multiple film height equate that the height of the folding multiple film in right side is greater than the folding multiple film height in left side.
After sealing, two folding multiple films in centre fold with packing bag internal layer respectively and are connected, and the left side folds multiple film and is connected with the packaging bag volume surrounding is folding, folding film again in right side and packaging bag volume surrounding formation cornerite folding connection of structure.
The folding multiple film of packing sack of the present utility model all be through twice folding, and the height of the folding multiple film design in right side is higher than the folding multiple film of other packing sacks, it is folding to form angle wrapping structure, can effectively solve blowout prevention ash problem.Save simultaneously lining paper, saved cost.

The folding multiple film 1 in left side, middle folding multiple film 2, the folding multiple film 3 in right side, packing money 4.
The specific embodiment
Embodiment 1: comprise packaging bag body and packing sack, the packing sack is divided into three sections, be followed successively by the folding multiple film 1 in left side, middle folding multiple film 2, the folding multiple film 3 in right side, the folding multiple film 1 in left side is highly equal with middle folding multiple film 2, and the height of the folding multiple film 3 in right side is greater than the height of the folding multiple film 1 in left side.
During sealing, the folding multiple film 2 in two centres is folded to respectively the packaging bag body internal layer, the folding multiple film 1 in left side is folded to packaging bag body at the packaging bag body skin, and the position of the folding multiple film 3 in right side folding multiple film 3 in the middle of the packaging bag body skin is folded to forms angle wrapping structure.The folding multiple film 1 in left side after will folding then, middle folding multiple film 2, the folding multiple again doubling of film 3 in right side well both can with pack linear slit 4.
