Abstract

The invention discloses a woven bag internally covering film. The internally covering film comprises the components by the weight percentage: 75%-85% of EVA 14-2; 15%-10% of LLDPE 18; 6%-3% of HDPE 9455; and 4%-2% of linear 7042 or 7047. The woven bag internally covering film can be directly internally adhered to woven cloth, replaces an internally covering film having a layer structure; and the woven bag internally covering film has smooth surface, has strong adhesion ability on the woven cloth, and reduces the manufacturing cost of a woven bag with the internally covering film.

Description

In a kind of woven bag, cover and use film
Technical field
The present invention relates to a kind of plastic film material, especially a kind of thin-film material for using at woven bag internal surface overlay film.
Background technology
Interior coated knitted bag is widely used in the industries such as chemical industry, agricultural, food, cement, and it had both accepted the high advantage of woven bag tensile strength, had again resistance to air loss and moistureproofness that bag film is good, was a kind of typical compound package material.Especially the interior coated knitted bag that the cylinder weaving cloth of usining is made as base cloth, have especially that anti-pull-off force is strong, resistance to air loss good, moistureproof, overlay film difficult drop-off, bear that internal gas pressure ability is strong, outward appearance no longer includes the advantages such as the former flounce of outer multiple film woven bag exists, intensity is not impaired, and fundamentally solved in the past the original process by manually turning over bag.
Internal layer membrane material for the production of interior coated knitted bag in prior art adopts 2 layers or 3-tier architecture more, its objective is when making thin-film material there is smooth internal surface, can be attached to securely on braiding base cloth, CN 202742779 U disclose a kind of multiple woven bag film, this multiple woven bag membrane body comprises A surface layer, sandwich layer, B surface layer, A surface layer, sandwich layer, B surface layer superposes and is made by co-extrusion to successively, although the bag mould material of this structure has solved interior film strength, antistatic effect and inner membrance adhesion problem, but, need in process of production to adopt multimode coextrusion head could form film body, and multimode coextrusion head equipment price is higher, increased the manufacturing cost of interior coated knitted bag.In addition, this film with layer structure for guarantee three-decker complete and trilaminate material evenly, the thickness of its film forming is also restricted, and can not use film for covering in thinner interior coated knitted bag.
Summary of the invention
The technical problem that invention will solve: provide in a kind of woven bag and cover with film, in this woven bag, cover with film and stick in woven cloth in can be directly, substitute have layer structure in cover with film, in this woven bag, cover and use film smooth surface, adhesive ability to woven cloth is strong, has reduced the manufacturing cost of interior coated knitted bag.
The technical scheme that technical solution problem is taked:
In cover with a film, the weight percent of described interior overlay film component is:
EVA 14-2 75%—85%；
LLDPE 18 15%—10%；
HDPE 9455 6%-3%；
Linear 7042 or 7,047 4%-2%.
As improvement of the present invention: the weight percent of described interior overlay film component is:
EVA 14-2 80%；
LLDPE 18 12%；
HDPE 9455 5%；
Linear 7042 or 7,047 3%.
Beneficial effect: cover in woven bag of the present invention with film owing to reasonably defining material component and the mixing ratio of covering use film in woven bag, make to cover in woven bag of the present invention with film and stick in woven cloth in can be directly, both guaranteed the surface property that overlay film is smooth, in making again, cover with film woven cloth is had to good adhesive ability, therefore, in woven bag of the present invention, cover with film can substitute in prior art, by base layer and adhesive linkage, formed have layer structure in cover with film, only need in process of production single mode head to extrude, adopt multimode coextrusion head productive zone structure in cover the less investment with film film-forming apparatus, floor space and space are little, save electric energy, reduced the manufacturing cost of interior coated knitted bag.
Embodiment
Below to covering with film and be described in further detail in woven bag of the present invention.
Embodiment 1
In cover with a film, the weight percent of described interior overlay film component is:
EVA 14-2 85%；
LLDPE 18 10%；
HDPE 9455 3%；
Linear 7042 or 7,047 2%.
Embodiment 2
In cover with a film, the weight percent of described interior overlay film component is:
EVA 14-2 75%；
LLDPE 18 15%；
HDPE 9455 6%；
Linear 7042 or 7,047 4%.
Embodiment 3
In cover with a film, the weight percent of described interior overlay film component is:
EVA 14-2 80%；
LLDPE 18 12%；
HDPE 9455 5%；
Linear 7042 or 7,047 3%.
Raw material is put into individual layer inflation film manufacturing machine by the mixing ratio in above-described embodiment, and at 115 ℃～260 ℃ temperature, blowing forms in woven bag to be covered and uses film.
