Industrial Films: What are They and What Do They Do?
Industrial films are a type of adhesive film that are used in many different industries. They are most commonly used in the manufacturing and construction industries, but they can also be found in the medical and pharmaceutical industries. Industrial films are made from a number of different types of adhesive, and they can be used to adhere paper, plastic, metal, and other materials together.
Applications of BOPA films
In recent years, there has been a significant increase in the demand for industrial films. This is because these films have a number of unique properties that make them ideal for a variety of applications. Some of the key benefits of industrial films include:
Excellent clarity and gloss
High stiffness and tensile strength
Resistance to abrasion and chemicals
Excellent thermal stability
Low permeability to gases and vapors
Polyamide films are used in a wide range of industries, including packaging, printing, lamination, and medical devices. They are also used as coatings on other substrates such as metal, paper, and plastic.
Manufacturing process of industrial films
The manufacturing process of industrial films can be broadly classified into six steps: Material preparation, Film extrusion, Coating and laminating, Die cutting and slitting, Packaging and finishing. In the material preparation step, the polymer resins are melted and mixed in the desired proportions. The molten resin is then passed through a die to form a thin film which is cooled and solidified on contact with air.
In the film extrusion step, the solidified film is extruded through a series of interconnected dies that give it its desired thickness and width. The thickness of the film can range from a few micrometers to several millimeters. In the coating and laminating step, one or more coatings or adhesives are applied to one or both sides of the film.
Properties of industrial films
The properties of industrial films vary depending on the resin type. For example, BOPA is a clear film with high tensile strength and good optical properties. Polyamide is a tough film with good abrasion resistance. BOPET has good clarity and gloss, as well as high tensile strength and tear resistance. PP is a flexible film with high impact resistance. CPP is a heat sealable film with good gas barrier properties, while HDPE is a strong and durable film with excellent water barrier properties.
Advantages and disadvantages of industrial films
Each type of industrial film has its own unique advantages and disadvantages. For example, BOPA polyamide is strong and durable but can be expensive; HDPE is affordable but not very durable; LDPE is affordable and durable but not very strong.
It is important to understand the advantages and disadvantages of each type of industrial film before selecting the right film for your application. Doing so can help you to select the best film for your needs while avoiding any potential problems.
