The polyester film is called polyester film light sheet polyester film photosensitive paper polyester film tin benzene film cellophane release film, in order to protect the printing part from fading and damage, a plastic film is pasted on the surface of the polyester film, the film is required to be very transparent, has good toughness, uniform texture and no air bubbles, and the surface is very flat, so polyester printing films are used in the prior art, the prior art mainly has two using modes, one mode is to directly cover the printed paper printed matter with the printed film, and other products with the surface difficult to print, such as metal shell packaging, if the product needs to be printed on the surface, another brushing mode is required to be directly used for printing characters and patterns on the surface of the printed film, and then the printed film is covered on the surface of the product, so as to finish the printing of the packaging shell. The prior polyester printing film has the following defects:
1. the existing polyester printing film is generally connected by using a plasticizer in the production process, so that the polyester printing film is not beneficial to environmental protection, and the application range of the printing film is easily influenced.
2. The current printing films have good toughness and can protect printed matters, but the acid and alkali resistance is poor, medicine descriptions can be pasted on the surfaces of a plurality of chemical medicine bottles at present, and the current printing films are easily corroded by acid and alkali when the specifications on the surfaces of the chemical medicine bottles are protected, so that the printed matters cannot be protected.
3. The current printing film has two modes in use, one mode is to cover the surface of a printing product, the other mode is to directly print on the surface of the film, and most polyester materials are difficult to print and are easy to cause the situation that printed characters and patterns fall off.
To this end, we propose an environmentally friendly polyester printed film for solving the above problems.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an environment-friendly polyester printing film to solve the problem that proposes among the above-mentioned background art.

Preferably, the core layer accounts for 80% -90% of the total mass of the printing film, the polyester substrate consists of bright polyester chips and recycled chips, and the bright polyester chips account for 20% -30%.
Preferably, the upper surface layer and the lower surface layer are both composed of bright polyester chips and silicon-containing chips, the percentage of the bright polyester chips is 70% -80%, the concentration of silicon dioxide in the silicon-containing chips is 3000ppm, and the particle size is 3.9 um.
Preferably, the printing layer is made of PETG copolyester.
Preferably, the acid-base prevention layer is an acrylic adhesive coating and is fixedly connected with the surface of the printing layer in a coating mode.
Preferably, the adhesive layer is a thermoplastic polymer adhesive.
Compared with the prior art, the beneficial effects of the utility model are that:
1. the utility model discloses the sandwich layer contains the CHDM modified film, need not use the plasticizer can be good connect the top layer from top to bottom, and environmental protection more has also avoided the condition that the application range that leads to because of the environmental protection problem reduces simultaneously.
2. The utility model discloses the surface scribbles ya li ke and glues acid-base layer, except having good toughness, still possessed the function of acid-base prevention, and protective properties is better.
3. The utility model discloses be equipped with PETG copolyester printing layer, PETG copolyester environmental protection more is and very easy printing, has avoided the condition that the typeface pattern drops to appear when the printing.
