Abstract
The invention discloses a transparent winding film which is characterized by comprising the components by weight percent: 95-98% of linear polyethylene, 2-5% of ethylene, and tackifier. The transparent winding film is low in cost, reduces the production cost by 27-21% and is lower in influence on the environment during production.
Description
Technical field
The present invention relates to a kind of winding film, particularly a kind of transparent winding film belongs to the film manufacturing technology field of twining.
Background technology
Twine film and be stretched film again, domestic is base material the earliest with PVC, and DOA is the softening agent self-adhesion production PVC winding film of having held concurrently.Because reasons such as environmental issue, cost high (PE is than great relatively, and the unit packaging area is few), stretchiness differences, progressively be eliminated when beginning to produce the PE stretched film when 1994～nineteen ninety-five is domestic.The PE stretched film was self adhesive material before this with EVA, but its cost is high, flavoursome again, and the back development uses PIB, VLDPE to be self adhesive material, and base material is the side of being with LLDPE now, comprises C4, C6, C8 and metallocene PE (MPE).
Stretch wrap film is at normal temperatures, utilizes mechanical stretching device or the manual deformation stress that film is stretched and produced by force, goods is wrapped be convenient to transportation, and a kind of packaging means of storage is unusual a kind of packaged form of waterside in the world at present.Adopt import resin and the advanced stream film that spreads out to extrude production technique.It is good, tear-resistant to have tensile property, and penetration-resistant is strong, and transparency is high, and autohension is good and relaxation shrinkage is high, packing closely, can be not loose etc. characteristics.Can be widely used in single-piece or pallet packing and other enlacement packagings such as industrial chemicals, chemical fertilizer, food, electronic product, light textile goods.
The Application Areas of stretched film is very wide, mainly is to be used with pallet, and scattered commodity are put in order the collection packing, replaces baby container.Because it can reduce batch transportation of cargo packing cost more than 30%, thereby be widely used on the whole collection packing of multiple products such as five metals, mineral products, chemical industry, medicine, food, machinery; In the storehouse reservation field, utilize the stretch wrap film pallet packing to carry out the solid storing abroad, to save space and occupation of land also morely.
At present, though the winding film tensile property of using on the market is better, its production cost is bigger, and is big to environmental influence, is unfavorable for environmental protection.
Summary of the invention
It is low that technical problem to be solved by this invention provides a kind of production cost, the transparent winding film little to environmental influence.
In order to solve above-mentioned technical problem, technical scheme of the present invention is:
A kind of transparent winding film is characterized in that comprising following weight percent component:
Linear polyethylene 95-98%
Tackifier 2-5%.
Described tackifier are the EVA resin.
Transparent winding film cost of the present invention is low, has reduced the production cost of 27-21%, and when producing, has fewer environmental impacts.
Embodiment
Embodiment 1
With weight percent is after 95% linear polyethylene and weight percent are 5% EVA mixed with resin, to be heated to melt, and the raw material of melt shape is pushed, and carries out curtain coating at last, obtains product of the present invention.
Embodiment 2
With weight percent is that 98% linear polyethylene and weight percent are after 2% DOA mixes, to be heated to melt, and the raw material of melt shape is pushed, and carries out curtain coating at last, obtains product of the present invention.
Embodiment 3
With weight percent is that 96% linear polyethylene and weight percent are after 4% DOA mixes, to be heated to melt, and the raw material of melt shape is pushed, and carries out curtain coating at last, obtains product of the present invention.
Embodiment 4
With weight percent is after 97% linear polyethylene and weight percent are 3% EVA mixed with resin, to be heated to melt, and the raw material of melt shape is pushed, and carries out curtain coating at last, obtains product of the present invention.
The foregoing description does not limit the present invention in any way, and every employing is equal to the technical scheme that replacement or the mode of equivalent transformation obtain and all drops in protection scope of the present invention.
