How to Make High-Performance Heat Shrink Film PETG Polyester Slices

Heat shrink film PETG polyester slices are a kind of high-performance heat shrink material, which are made by a process of vacuum drying, melt extrusion, rapid cooling casting, uniaxial or biaxial stretching, cooling setting, winding, and cutting. In this article, we will introduce the details of each step, the advantages and applications of this product, and how to contact us for more information.

The Process of Making Heat Shrink Film PETG Polyester Slices

The process of making heat shrink film PETG polyester slices is as follows:

• Vacuum drying: The amorphous PETG polyester slices are placed in a vacuum dryer to remove the moisture and low molecular substances, which improves the melt viscosity and stability, and prevents bubbles and color difference.
• Melt extrusion: The dried PETG polyester slices are fed into a single-screw or twin-screw extruder, heated to 200~250℃, melted into a uniform melt, and then extruded into thin slices through a flat or circular die head.
• Rapid cooling casting: The extruded thin slices are quickly cooled on a cooling roller, making them solidify into amorphous cast slices, which maintain their high transparency and low shrinkage rate.
• Uniaxial or biaxial stretching: The cast slices are heated to 80~120℃, and stretched in the longitudinal or transverse or both directions by a certain multiple, which generates orientation stress, and improves their strength and shrinkage performance.
• Cooling setting: The stretched film is cooled below room temperature, making it set, eliminating stress, and preventing shrinkage and deformation.
• Winding and cutting: The cooled and set film is wound and cut according to certain specifications, inspected for its quality and performance, and packaged for storage.

The Advantages of Heat Shrink Film PETG Polyester Slices

Heat shrink film PETG polyester slices have the following advantages:

• Quality stability: Heat shrink film PETG polyester slices use high-quality raw materials and advanced production technology, ensuring the dimensional accuracy and physical properties of the products, which are not easy to deform, bubble, or crack.
• Heat resistance: Heat shrink film PETG polyester slices have a high glass transition temperature (Tg), which can maintain good mechanical strength and chemical resistance at high temperatures, suitable for various heat shrink equipment.
• Film-forming strength: Heat shrink film PETG polyester slices have excellent film-forming performance, which can closely fit the surface of various shapes of objects, presenting a smooth, bright, and transparent effect, increasing the aesthetics and added value of the products.

The Applications of Heat Shrink Film PETG Polyester Slices

Heat shrink film PETG polyester slices are widely used in the following fields:

• Digital printing substrate: Heat shrink film PETG polyester slices can be used as digital printing substrates, which have good printing adaptability and ink absorption, and can print clear, bright, and durable images.
• Furniture release film: Heat shrink film PETG polyester slices can be used as furniture release film, which covers the surface of furniture, protecting it from scratches, stains, water vapor, etc., extending the service life of furniture.
• Various label base films: Heat shrink film PETG polyester slices can be used as various label base films, which are used to make barcodes, QR codes, anti-counterfeit labels, trademark labels, etc., which have high transparency and tear resistance, convenient for identification and use.
• Plastic containers: Heat shrink film PETG polyester slices can be used as packaging materials for plastic containers, which wrap various shapes and sizes of plastic bottles, cans, boxes, etc., improving the sealing and moisture resistance of the products, extending the shelf life of the products.
• Electronic labels: Heat shrink film PETG polyester slices can be used as carrier materials for electronic labels, which are used to make radio frequency identification (RFID) tags, electronic shelf labels (ESL), etc., which have high electrical stability and anti-interference ability, improving the data transmission speed and accuracy.
• Thermal transfer release protection: Heat shrink film PETG polyester slices can be used as thermal transfer release protection materials, which protect the patterns on the thermal transfer paper from being damaged or contaminated, providing smooth, uniform, and bubble-free transfer effects during the transfer process.
• Building decoration composite: Heat shrink film PETG polyester slices can be used as building decoration composite materials, which are combined with metal, glass, wood, and other materials, making decorative panels with different colors, textures, and effects, increasing the beauty and personality of buildings.
