Description

Technical Field

[0001] The utility model relates to the technical field of shrink film equipment, in particular to a POF anti-static heat shrink film. Background Art

[0002] POF heat shrink film is a high-quality, efficient and environmentally friendly packaging material. POF heat shrink film is widely used in the packaging of products in various industries such as food and beverages, handicrafts, electronic appliances, mechanical parts, etc. It can prevent moisture, water and dust, and effectively protect electronic products, machinery and other precision products.

[0003] For example, the utility model patent disclosed in the publication number CN211251613U is a POF antistatic heat shrink film, which includes a first substrate layer, an adhesive layer, a printing layer, an antistatic layer, a corona layer, and a second substrate layer laminated in sequence from top to bottom. The utility model can coat the antistatic agent on the heat shrink film substrate by coating, and the process is simple and convenient. Compared with the heat shrink film produced by blending and melting the antistatic agent, the surface resistance of the product is less than 109Ω, which improves the antistatic effect of the product; the utility model uses two substrates to "wrap" the antistatic agent, which plays a protective role in the antistatic layer, and can prevent the antistatic agent from falling off due to long-term friction when the heat shrink film is used, thereby extending the antistatic effect of the packaging material; the utility model can also "wrap" the printing layer inside the two substrates, which can prevent the printing pigment from falling off while playing a conspicuous role.

[0004] Although the above shrink film has certain antistatic properties, the above shrink film has insufficient stability in conducting static electricity, and it is not convenient to perform all-round antistatic operations on the inside of the shrink film. Therefore, a POF antistatic heat shrink film is urgently needed to solve the above problems. Utility Model Content
