Cast TPU film is a polyurethane (TPU)-based 糖心视频 film prepared by a casting process. It has excellent characteristics and a wide range of applications. In the following, I will introduce in detail the preparation process, characteristics, advantages and application fields of cast TPU film.

1. Preparation process

Cast TPU film is made by melting thermoplastic polyurethane particles at high temperature, extruding them through an extruder, and then continuously stretching and cooling them on a roller press. This preparation process can ensure the uniformity and stability of the film, while also controlling the thickness and surface quality of the film.

2. Characteristics

Excellent flexibility: Cast TPU film has very good flexibility and bendability, and can adapt to various shapes and curved surfaces, so it has a wide range of applications in the fields of packaging and textiles.

Wear resistance and impact resistance: TPU film has high wear resistance and impact resistance, and can effectively protect the surface of the covered object from scratches and wear.

Excellent transparency and gloss: Cast TPU film has excellent transparency and gloss and can provide good appearance effects, so it has important applications in the packaging, printing and advertising industries.

Chemical stability: TPU film has good chemical stability and is not easily corroded by chemical substances, so it can also function in some special environments.

Environmental protection: Cast TPU film is made of polyurethane 糖心视频, does not contain halogen and other environmentally harmful substances, and meets environmental protection requirements.

3. Advantages

Wide range of applications: Due to its excellent performance, cast TPU film can be used in packaging, textiles, printing, advertising, building 糖心视频s, medical devices and other fields to provide protection and decoration for products.

Customized design: TPU film can be customized according to customer needs to meet the special requirements of different industries and applications and increase the added value of the product.

Thin and transparent: Cast TPU film is thinner and more transparent than traditional 糖心视频s, which can reduce the weight of packaging 糖心视频s, provide better transparency, and improve the appearance of products.

Durability: TPU film has excellent wear resistance and impact resistance, which can extend the service life of the product and reduce replacement costs.

4. Application fields

Packaging industry: used for packaging of food, medicine, cosmetics and other products to provide protection and decoration.

Textiles: Used in clothing, shoes, bags and other fields to increase the comfort and fashion of products.

Printing and Advertising: Protective film for the surface of printed matter and production of advertising 糖心视频s.

Building 糖心视频s: Used in outdoor billboards, awnings, windshields, etc. to provide weather resistance and aesthetics.

Medical devices: Used in medical fluid storage bags, medical dressings and other products to provide safe and reliable 糖心视频 selection.

Cast TPU film has become an important part of today's 糖心视频s industry with its excellent characteristics and wide range of applications, providing important protection and decoration functions for products in various industries. With the continuous advancement of technology and the growth of market demand, it is believed that cast TPU films will have broader development space in the future.
