Description

A kind of in-mold labels for PET injection molding of high transparency

Technical field

The utility model relates to the packing box fields of high-end cigarette, wine, cosmetics and gift, more particularly to a kind of high The transparent in-mold labels for PET injection molding.

Background technique

Explanation of nouns:

PET plastic container: PET is commonly called as polyester resin, is most important kind in thermoplastic polyester.PET plastic is being packed It is processed to plastic containers, packaging film, coiled material, beer bottle etc. in field, is not only widely used in packaging soda, drinks Water, fruit juice, ferment and tea beverage etc., and the various fields such as food, chemical industry, Key works Drug packing are widely used in, it is current usage amount One of maximum beverage packaging material.

Injection molding: when plastic injection produce plastic products a kind of method, injection molding machine by the plastics of melting using pressure infuse into Desired various plastic parts are obtained in plastic product mold, after cooling and shaping.

In-mold labels: printed commecial label image printed sheet (back side band hot melt adhesive) is directly placed into plastics casting with manipulator Mold region in mould machine is combined together label and container by being blow molded or being molded, and forms a complete packing container. Maximum feature using in-mold label container is exactly label and bottle body on the same surface, feels label colour picture and text as straight Connect that be printed on bottle body surface general.

PET-IML technique: in-mold labels are first sent by manipulator by mould inner wall, the temperature of bottle base carries on the back in-mold labels The solidification glue in face dissolves, so that in-mold labels integrally combine with pet container.

For the decorative appearance of pet container, commonly used method is as follows: 1. directly on pet container silk-screen content, this Method republishes after need to handling suitable for explanation and simple patterned display, and bottle body surface；2. with Membrane cover mark is shunk, in the industry Also there is application, also need two degree of processing and Product recycling is difficult；3. transfer technique directly manufactures device content at transfer Film is transferred in vessel surface with thermal transfer or water transfer printing method, and process is not only cumbersome but also pollutes environment；4. adhesive label is used, Adhesive label has adhesivity, but pet container polarity is strong, and it is easy to appear bubbles, corrugation for label when labeling, so both shadows The bonding effect of labelling is rung, and influences the aesthetics of container, especially for transparent vessel, disadvantage is more prominent.

In order to realize that better transparent wrapper label decorative effect and anti-counterfeiting performance, packaging industry develop always PET- IML technology, but material due to current in-mold labels and manufacturing process have limitation, are not able to achieve in-mold labels perfection fitting PET The effect of container, it is most important the disadvantage is that in-mold labels are not transparent enough.

Utility model content

The purpose of this utility model is to provide a kind of in-mold labels for PET injection molding of high transparency.

Technical solution adopted in the utility model is:

A kind of in-mold labels for PET injection molding of high transparency, including be stacked from bottom to up solid state bonds oxidant layer, Transparent the first PET film, pattern layer, transparent the second PET film and protective layer.

As an improvement of the above scheme, protective layer is antistatic light oil reservoir.

As an improvement of the above scheme, the second PET film is 30#PET film.

As an improvement of the above scheme, thickness of the thickness of the first PET film less than the second PET film.

The utility model has the beneficial effects that for being fused to pet container surface below this in-mold labels, in-mold labels and There is PET material in the fusion face of PET container, and the fusion face of the two has good chemical similarity, is able to achieve and ties well It closes, not only solves the puzzlements such as conventional labels easy to fall off, damage, mildew, and can also ensure that labeling precision and yield rate；It is special Be not PET film itself transparency it is just very high, the edges of entire in-mold labels and pet container one integrated mass improve appearance Brand image.

Detailed description of the invention

The utility model is described in further detail with reference to the accompanying drawing:

Fig. 1 is the cross-sectional view of in-mold labels.

Specific embodiment

Referring to Fig.1, the utility model is a kind of in-mold labels for PET injection molding of high transparency, including layer from bottom to up The solid state bonds oxidant layer 1 of folded setting, the first transparent PET film 2, pattern layer 3, transparent the second PET film 4 and protective layer 5, wherein Substrate of second PET film 4 as pattern layer 3, protective layer 5 is for preventing the second PET film 4 to be scraped off.In the present embodiment, second PET film 4 is 30#PET film, has taken into account the manufacturing cost of in-mold labels, i.e. cost is roughly the same with other film class labels.

Below this in-mold labels, i.e. the first PET film 2, for being fused to pet container surface, in-mold labels and pet container Fusion face have a PET material, the fusion face of the two has good chemical similarity, is able to achieve and combines well, not only solves The puzzlements such as conventional labels of having determined are easy to fall off, damage, go mouldy, and can also ensure that labeling precision and yield rate；Especially PET The transparency of film itself is just very high, and the edge and pet container one integrated mass of entire in-mold labels improve appearance brand shape As.

As preferred embodiment, protective layer 5 is antistatic light oil reservoir, can be existed to avoid two adjacent in-mold labels Cause to form double sheet because electrostatic is bonded to each other during processing.It clamps, turn one by one convenient for manipulator after adopting the above scheme It moves, realizes production automation.

As preferred embodiment, the thickness of the thickness of the first PET film 2 less than the second PET film 4, it is ensured that labelling The first PET film 2 incorporates pet container almost in journey.

Certainly, the design creation is not limited to above embodiment, and the combination of the various embodiments described above different characteristic can also To reach good effect.Those skilled in the art can also make without departing from the spirit of the present invention It is all included in the scope defined by the claims of the present application with deformation or replacement, these equivalent variation or replacement.
