Abstract

A kind of Composite Puncture film production process first selects PETG contracting film, and different thickness can be selected according to product effect, and composite layer can select the film of different materials to carry out two-layer compound using compounding machine；Material can change under the conditions of 50 DEG C of temperature, the matching of reasonable setting machine speed and drying temperature is needed in compound tense, material must be dried and be cooled down within the unit time, make material that modification not occur, and can carry out curing 24 hours at 35 DEG C of low temperature later；Molding packaging film is cut, is puted the palms together before one, inspection product, packaging.The beneficial effects of the present invention are: that rear flexibility is made is preferable for E-PETG shrink film, but it is after stiffness difference that PE shrink film and the progress of PETG film is compound, it can solve the stiffness of material after selecting high-intensitive composite glue to make E-PETG shrink film and transparent PET G film that the stiffness for increasing shrink film, two kinds of materials be combined to combine well, damage resistibility, shrink positioning, fold and cost problem.

Description

A kind of Composite Puncture film production process
Technical field
The present invention relates to kind of a production for Composite Puncture film, especially a kind of Composite Puncture film production process.
Background technique
In recent years, the product packed using contraction film label is more and more, and since packing material has different shapes (to have Round, oval, rectangular, bottle-type diametrically under it is inconsistent etc.), used respectively in different fields.Shrink film will adapt to difference The packaging of product, which is shunk, to be required, fixed from label design, the shrinking percentage of label film, printing coefficient of friction, the stiffness of shrink film, contraction Tear-resistant break by a fall of label requires after position, constricted fold, contraction.But shrink film used at present is primarily present in the market Because thickness reason stiffness is poor, Special-shaped object poor location and shrink after there are folds, as the extension of tag memory time is such Problem can be more serious.Therefore it is badly in need of a kind of more excellent shrink film product to fill up the blank in market.
Summary of the invention
The purpose of the present invention is design a kind of Composite Puncture film production process structurally reasonable, using effect is good.
The technical scheme is that a kind of Composite Puncture film production process, it is characterised in that: first select PETG contracting film (first layer), can select different thickness according to product effect, and composite layer (second layer) can select the film benefit of different materials Two-layer compound is carried out with compounding machine；Material can change under the conditions of 50 DEG C of temperature, need reasonable setting machine in compound tense The matching of speed and drying temperature, material must be dried and be cooled down within the unit time, make material that modification, Zhi Houke not occur To carry out curing 24 hours at 35 DEG C of low temperature；Molding packaging film is cut, is puted the palms together before one, inspection product, packaging.
The materials such as PE shrink film, milky white PETG, transparent PET G can be selected in the composite material, not according to material Keep itself and the progress of PETG film compound with performance, achieves the desired results, while material cost can be saved.
The machine speed is: 150 ~ 200m/min.
The drying temperature are as follows: 50 ~ 65 DEG C.
(cooling water temperature is controlled at 10 ~ 20 DEG C) must be dried and be cooled down to material in 1.5 ~ 3 seconds.
The beneficial effects of the present invention are: to be made rear flexibility preferable for E-PETG shrink film, but PE is shunk after stiffness difference Film and the progress of PETG film are compound, select high-intensitive composite glue to combine E-PETG shrink film and transparent PET G film well and increase It can solve the stiffness of material after adding the stiffness of shrink film, two kinds of materials to combine, damage resistibility, shrink positioning, fold and cost Problem.
The product that the present invention produces: tensile strength >=35N/15mm；Elongation at break (transverse direction) >=40%, longitudinal >= 500%；Shrinking percentage: lateral >=60%, longitudinal direction≤3%.
