PE metal polypropylene film is a material that covers the surface of polyethylene (PE) film with a metal film

Brief introduction

PE metal polypropylene film is a material that covers the surface of polyethylene (PE) film with a metal thin film. It has the advantages of high glossiness, good corrosion resistance, and airtightness, and is widely used in packaging, printing, decoration, and other fields.

2、 The preparation process of PE metal polypropylene film mainly includes the following steps:

1. Substrate treatment: Clean and treat the surface of the polyethylene substrate to ensure that the subsequent metal coating can firmly adhere to the substrate surface.
2. Vacuum coating: evaporating metal materials (such as aluminum, copper, nickel, chromium, etc.) onto the surface of PE substrate to form a layer of metal film. This process needs to be carried out under vacuum conditions to ensure that there is no oxygen present during the metal evaporation process, avoiding oxidation reactions and affecting the quality of the metal film.

3. Sealed Composite: Composite PE substrate coated with metal with other materials to improve the durability and performance of PE metal polypropylene film. Composite materials can be other plastic films, paper, adhesives, etc.
   

3、 Application FieldsPE metal polypropylene filmWidely used in high-end gift packaging, cosmetics packaging, food packaging, electronic product packaging and other fields. Its main advantages include:

1. High end texture: The surface of PE metal polypropylene film has a metallic texture and high glossiness, which can increase the texture and value of the product.
2. Good protective performance: PE metal polypropylene film can protect packaging materials from damage caused by oxidation, moisture, light, etc.
3. Good printing performance: The surface of PE metal polypropylene film is flat and smooth, which can achieve high-definition and high-precision printing effects.

4. Recyclability: PE metal polypropylene film material has recyclability and meets environmental protection requirements.
   

4、 The product quality of PE metal polypropylene film is affected by multiple factors, such as the thickness, uniformity, adhesion, and corrosion resistance of the metal film. In order to ensure product quality, the following aspects of control need to be carried out:

1. The quality of the substrate: The quality of the polyethylene substrate directly affects the quality of the PE metal polypropylene film, so it is necessary to choose high-quality substrates.
2. Selection of metal materials: Different metal materials have different properties, and choosing the appropriate metal material can improve the quality of PE metal polypropylene film.
3. Control of vacuum coating process: The vacuum coating process requires controlling parameters such as temperature and air pressure to ensure the quality of the metal film.

4. Control of composite process: The composite process requires controlling parameters such as temperature and pressure to ensure the quality of the PE metal polypropylene film after composite.
   

5、 Summary

PE metal polypropylene film is a high-end and high-quality packaging and decorative material with good protective and printing properties. The preparation of PE metal polypropylene film requires controlling multiple factors to ensure product quality. With the increasing awareness of environmental protection, recyclable PE metal polypropylene film will become more popular.
