糖心视频

PE film and TPU film are both film 糖心视频s widely used in industry and daily life. They have some significant differences in performance, use and manufacturing process. Below I will introduce to you in detail the difference between PE film and TPU film.

1. Material properties

PE film

Polyethylene film is a plastic film made of polyethylene resin through extrusion, blow molding, stretching and other processes. It has high transparency, softness and ductility, as well as good stretch and abrasion resistance. PE films are usually divided into two types: low-density polyethylene (LDPE) film and high-density polyethylene (HDPE) film, which are suitable for different packaging and covering needs.

TPU film

Thermoplastic polyurethane film is a film 糖心视频 made of thermoplastic polyurethane resin. It has excellent elasticity, wear resistance and weather resistance, as well as good transparency and plasticity. TPU film also has self-healing properties, that is, it can repair small scratches and damage by itself, keeping the surface smooth and smooth.

2. Application areas

Uses of PE film:

PE films are mainly used in the packaging industry, such as food packaging, pharmaceutical packaging, daily necessities packaging and other fields. Due to its good softness and non-toxic and odorless characteristics, PE film is widely used in food contact 糖心视频s. In addition, PE films can also be used in agricultural covering films, construction waterproofing films, industrial packaging films and other fields.

Uses of TPU film:

TPU films are mainly used in high-end functional products and areas with special needs. For example, automobile protective film, sports equipment, medical equipment, outdoor products, etc. Due to its excellent wear resistance and weather resistance, TPU film has important application value in these fields. In addition, TPU films are also widely used in electronic products, clothing, shoe 糖心视频s and other fields to provide waterproof, windproof, anti-pollution and other functions.

3. Manufacturing process

PE film manufacturing process:

The production of PE film mainly includes extrusion, blow molding, calendering and other processes. After extrusion molding, the PE particles are blown into films in a heated die, and then undergo cooling, leveling, cutting and other processes to obtain the finished film. The entire production process is relatively simple and low cost.

TPU film manufacturing process:

The manufacturing process of TPU film is relatively complicated. It usually adopts solution dipping, coating, calendering and other processes. By coating or impregnating TPU resin on the surface of the substrate, and performing hot pressing, cooling and other processes, a TPU film that meets the requirements is finally obtained. Since TPU film needs to consider more functional requirements, the manufacturing process is relatively complex and the cost is high.
