Description

Heat-shrinkable polyester film with good printability

Technical Field

The utility model particularly relates to a polyester film technical field especially relates to a heat-shrinkable polyester film that printability is good.

Background

In the current domestic market, in consideration of environmental protection, environment-friendly shrink film products increasingly occupy more market shares, for example, PET for shrink films, Polystyrene (PS) and the like have a tendency to gradually replace PVC shrink films, wherein polyester shrink films are widely applied to products such as capacitors (heat shrinkable sleeve films), battery trademarks (longitudinally stretched films), PET bottle shrink labels (transversely stretched films) and the like due to large shrinkage rate of the polyester shrink films.

However, as the use expands, some problems still face to be optimized: in the use process of the polyester film, the film needs to be printed in some cases, but the conventional polyester film needs to be further improved in this respect, so that a polyester film with good printing property is demanded.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects existing in the prior art and providing a heat-shrinkable polyester film with good printing performance.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a thermal contraction polyester film that printability is good, includes the film body, the film body is including basic rete, and the opposite side of basic rete is equipped with anti ultraviolet layer, one side on anti ultraviolet layer is equipped with the insulating layer, and basic rete one side outer wall is equipped with glues glutinous layer, the one side of gluing glutinous layer is equipped with printing ink printing layer, and printing ink printing layer one side outer wall is equipped with the inoxidizing coating.

Further, the thickness of the film body is between 50um and 100 um.

Further, the base film layer is prepared by copolymerization modification of polyethylene glycol terephthalate.

Further, the adhesive layer is a low-temperature hot melt adhesive.

Further, the protective layer is a PE antistatic film.

Further, the ultraviolet-proof layer is a high-transparency PET film.

Further, the heat insulation layer is a transparent reflective heat insulation film.

The utility model has the advantages that:

1. through at this internal printing ink printing layer that sets up of film for the printing ability of film body obtains further promotion, thereby makes the printing performance of film body can satisfy people's user demand.

2. The protective layer is arranged outside the ink printing layer, and because the film is commonly used for electrical equipment, the condition of generating static electricity can often occur on the electrical equipment, the anti-static capacity of the film body is further realized by the arrangement of the protective layer, and the condition of damaging the film due to the static electricity is avoided.

3. Make the adhesive force of film body further obtain promoting through gluing the setting on glutinous layer, glue glutinous layer and be low temperature hot melt adhesive, its principal ingredients EVA resin is formed by ethylene and vinyl acetate copolymerization under high temperature and high pressure, because this film is often used for electrical equipment, electrical equipment during operation can produce a large amount of heats, and when the film body was heated, the adhesive force on glutinous layer can not descend at all, still has the adhesion nature more for printing ink printing layer laminating effect is better.
