Abstract
The utility model discloses dust-leakage-proof composite packaging paper. The dust-leakage-proof composite packaging paper is composed of a surface layer, an intermediate reinforcing layer and a hot seal layer. The surface layer and the intermediate reinforcing layer as well as the hot seal layer and the intermediate reinforcing layer are adhered by composite adhesives. The hot seal layer is made of breathable hot-seal polypropylene fiber non-woven fabric, the intermediate reinforcing layer is a polyester mesh towel film with high strength, the surface layer is a porous polyester or nylon film, and a first composite adhesive layer and a second composite adhesive layer are composite adhesives. The dust-leakage-proof composite packaging paper is guaranteed to have good breathability and dust leakage proofing after being composited and has good mechanical strength for heavy package.
Description
Technical field
The utility model belongs to packing, is specifically related to a kind of dust leakage composite packaging paper of heavy packaging high-strength degree.
Background technology
Wrapper commonly used is composited by trilaminate material, its ectomesoderm and internal layer are plastic sheetings, the middle level is paper, in order to make wrapper have permeability to air, usually the mode that adopts machinery to prick the hole is bundled into the breather hole of permeability on compound rear wrapper, but in use can cause the dust in packaging bag to reveal from the hole, cause pollution.
In order to address this problem, present common way is first to prick the hole on inside and outside double-layer films, and then compound, wrapper after compound is owing to there is no through hole on paper, can avoid the leakage of dust, but because the mechanical strength of film after pricking the hole sharply descends, therefore not be suitable for heavily packing.
Summary of the invention
The purpose of this utility model is to provide a kind of dust leakage composite packaging paper, is used for the packing of deoxidizer, desiccant.
The technical solution that realizes the utility model purpose is: a kind of dust leakage wrapper, enhancement layer and hot sealing layer by surface layer, middle level forms successively, bonding with compound adhesive between the enhancement layer in surface layer and middle level, bonding with compound adhesive between the enhancement layer in hot sealing layer and middle level.
The hot sealing layer material is the nonwoven polypropylene fabric with permeability to air and heat sealability, and the enhancement layer material in middle level is for having high-intensity polyester hairnet film, and the surface layer material is mylar or nylon film with holes, and compound adhesive adopts commercial compound adhesive.
The utility model compared with prior art, its remarkable advantage: the bundle hole film that has replaced general composite packaging paper internal layer with the nonwoven fabrics with heat sealability, increased again simultaneously the polyester hairnet film of high mechanical properties in the middle level, when having fine air permeability and dust leakage after assurance is compound, make it have the good mechanical strength that is suitable for heavily packing.
Description of drawings
Fig. 1 is the section-drawing according to the dust leakage composite packaging paper that the utility model proposes.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
A kind of dust leakage wrapper, enhancement layer 2 and the hot sealing layer 3 by surface layer 1, middle level forms successively, and be bonding with compound adhesive between the enhancement layer 2 in surface layer 1 and middle level, bonding with compound adhesive between the enhancement layer 2 in hot sealing layer 3 and middle level.
Wherein surface layer 1 material is mylar with holes, and enhancement layer 2 materials in middle level are for having high-intensity polyester hairnet film, and hot sealing layer 3 materials are the nonwoven polypropylene fabric with permeability to air and heat sealability, and compound adhesive adopts commercial compound adhesive.
A kind of dust leakage wrapper, be used for packing deoxidizer or desiccant, wrapper is cut into the width that needs, hot sealing layer 3 is inwardly packed into pack in the former of particles packing machine, perhaps be cut into the size that needs, for example be cut into 10cm*6cm, with capper, hot sealing layer 3 thermal synthesis left the packaging bag of an opening, deoxidizer or desiccant are packed into seal with capper after packaging bag.
