Abstract
The utility model relates to a packaging polyolefin (POF) heat shrink film with air holes and aims at providing a packaging POF heat shrink film with the air holes, according to which vent holes punching is not required during film packaging, and the packaging can be directly performed. The film comprises a POF heat shrink film. The film is characterized in that the air holes formed in arrays are formed in the POF heat shrink film. The POF heat shrink film provided by the utility model has the beneficial effects that as the air holes are already formed when the film is manufactured, the hole punching is not needed during the film packaging; for one way, the holes are punched when the film is packaged, and for another way, the holes are punched when the film is manufactured, the processing steps in the latter case is relatively simple, and the structure of a packaging machine is simplified.
Description
Technical field
The utility model relates to packing, particularly a kind of packaging POF Polyolefin Heat Shrinkable Film with air extractor vent.
Background technology
In order to protect the presentation quality of article surface, often use heat-shrinkable film, during use, earlier heat-shrinkable film is wrapped in the surface of article, shrink through the heat hot shrinkable film, heat-shrinkable film is fitted in the surface of article.Because the air in the heat-shrinkable film contraction process between article and the shrinkable film influences the contraction of film, therefore normally when the parcel heat-shrinkable film, heat-shrinkable film is stung upper air-vent, be beneficial to the discharge of air.This structure to coating machine has increased complexity, has also improved manufacturing cost.
The utility model content
The purpose of the utility model provides a kind of exhaust outlet pricking that when coating, do not need, the packaging POF Polyolefin Heat Shrinkable Film of the band air extractor vent that can directly pack.
In order to reach above-mentioned requirements, the utility model is realized through following technical scheme: it comprises the POF Polyolefin Heat Shrinkable Film, it is characterized in that on the POF Polyolefin Heat Shrinkable Film, being shaped on the air extractor vent of arrayed.
The spacing of said air extractor vent arrayed is 1mm-10mm * 1mm-10mm, and the diameter of air extractor vent is 0.1mm-1mm.
The pore-solids ratio of said air extractor vent is 10%-30%.
The packaging POF Polyolefin Heat Shrinkable Film of the band air extractor vent of making according to such scheme; Because this film makes air extractor vent during fabrication, therefore, just need be at acanthopore when coating; Although a kind of is acanthopore when coating; Another kind is when film is produced, just to sting the hole, and the latter's manufacturing procedure is simply many relatively, has also simplified the structure of wrapping machine.
Description of drawings
Fig. 1 is the front view of the packaging POF Polyolefin Heat Shrinkable Film of band air extractor vent.
Wherein: 1, POF Polyolefin Heat Shrinkable Film; 2, air extractor vent.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to describe.
Fig. 1 is the local section enlarged drawing of the packaging POF Polyolefin Heat Shrinkable Film of band air extractor vent.From figure, find out that it comprises POF Polyolefin Heat Shrinkable Film 1, on POF Polyolefin Heat Shrinkable Film 1, be shaped on the air extractor vent 2 of arrayed.The spacing A of air extractor vent 2 arrayed is 1mm-10mm * 1mm-10mm, and the diameter D of air extractor vent 2 is 0.1mm-1mm.The pore-solids ratio of air extractor vent 2 is 10%-30% (hole area/film size * 100%).
Claims (3)
1. be with the packaging POF Polyolefin Heat Shrinkable Film of air extractor vent, it comprises the POF Polyolefin Heat Shrinkable Film, it is characterized in that on the POF Polyolefin Heat Shrinkable Film, being shaped on the air extractor vent of arrayed.
2. the packaging POF Polyolefin Heat Shrinkable Film of band air extractor vent according to claim 1, the spacing that it is characterized in that said air extractor vent arrayed is 1mm-10mm * 1mm-10mm, the diameter of air extractor vent is 0.1mm-1mm.
