Embodiment 1

[0016] A kind of environment-friendly film production technology, comprises the following steps:

[0017] S1. Put the raw material into the heating equipment to heat and soften to obtain the softened film raw material;

[0018] S2. Add additives to the film raw material, and put the raw material into the coating machine;

[0019] S3. Then inject the adhesive through the pressure of the coating head cavity. The top of the coating head is a slit. When coating, the adhesive flows out evenly from the slit of the coating head as the backing paper moves. And coated on the surface of the backing paper;

[0020] S4. Obtain a thin film after waiting for cooling.

[0021] In step S1 of this embodiment, the raw material is polyvinyl chloride.

[0022] In step S2 of this embodiment, the auxiliary agent includes acid anhydride blocking end group, propylene copolymerization and stearic acid metal salt.

[0023] In step S3 of this embodiment, the operating speed of the coating machine is...
