Technical Field

[0001] This utility model relates to the field of PE film technology, specifically to a PE film with good puncture resistance. Background Technology

[0002] The most common problem with products during transportation is wear and tear, which can cause significant economic losses. PE protective film can protect products from pollution, corrosion, and scratches during production, processing, transportation, storage, and use, preserving the original smooth and glossy surface of the product and improving product quality and market competitiveness.

[0003] Although existing PE protective films can be used to protect products, they have poor puncture resistance. Sharp objects can penetrate the protected product when in contact with them, resulting in poor protection. Summary of the Invention

[0004] The purpose of this invention is to provide a PE film with good puncture resistance, which has the advantages of high strength, strong puncture resistance and good wear resistance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a PE film with good puncture resistance, comprising a film body, the film body comprising a base layer, a reinforcing layer provided on both the upper and lower sides of the base layer, an anti-puncture layer provided on the opposite side of the two reinforcing layers, and an abrasion-resistant layer provided on the opposite side of the two anti-puncture layers, the base layer comprising a low-density polyethylene film, and a high-density polyethylene film provided on both the upper and lower sides of the low-density polyethylene film.

[0006] To improve the strength of the membrane, the reinforcing layer is preferably a CPD film, which is a preferred PE membrane with good puncture resistance according to this utility model.

[0007] To improve the puncture resistance of the membrane, the preferred PE membrane of this invention with good puncture resistance is made of high molecular weight polyethylene resin.

[0008] To improve the surface wear resistance of the membrane, the preferred material of the wear-resistant layer in this utility model, which is a PE membrane with good puncture resistance, is PVC resin.

[0009] To improve anti-slip properties, a preferred PE film with good puncture resistance according to this invention has multiple evenly distributed anti-slip protrusions on the opposite sides of the two wear-resistant layers.

[0010] To improve the connection strength between the layers, in the preferred embodiment of this utility model of a PE film with good puncture resistance, the base layer, reinforcing layer, puncture-resistant layer and wear-resistant layer are all bonded together with an adhesive between adjacent layers.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] The membrane body includes a base layer, which consists of a low-density polyethylene (LDPE) film. High-density polyethylene (HDPE) films are applied to both the top and bottom sides of the LDP film. This composite of high-density and low-density polyethylene films gives the membrane body good puncture resistance. The reinforcing layer is a CPD film, characterized by good transparency, high gloss, and excellent heat resistance. The puncture-resistant layer is made of high-molecular-weight polyethylene resin, which improves the puncture and tensile strength of the membrane body, making it less prone to damage during use. The wear-resistant layer is made of PVC resin, which has high strength and good wear resistance, improving the wear resistance of the membrane body's surface and protecting the puncture-resistant layer. Multiple evenly distributed anti-slip protrusions are provided on opposite sides of the two wear-resistant layers, enhancing the membrane body's wear resistance, extending its service life, and increasing surface friction, making it less likely to slip during use.
