An Insight into BOPP Thermal Lamination Film（1）
ฟิล์มเคลือบด้วยความร้อน
In the realm of packaging materials, การตีป๊อป (Biaxially Oriented Polypropylene) thermal lamination film stands out as a versatile and high-performance option. This blog post aims to provide a comprehensive understanding of BOPP thermal lamination film, its characteristics, แอปพลิเคชัน, and the process of lamination.
What is BOPP Thermal Lamination Film?
BOPP thermal lamination film is a type of plastic film made from polypropylene, which undergoes a process of biaxial orientation to enhance its physical properties. The film is then coated with a layer of EVA (Ethylene Vinyl Acetate) hot melt glue, making it suitable for thermal lamination. This process involves bonding two or more layers of material together using heat and pressure to create a strong, ทนทาน, and aesthetically pleasing finish.
Characteristics of BOPP Thermal Lamination Film
- Environmentally Friendly: BOPP thermal lamination film is non-toxic and does not emit hazardous gases or volatile content during the lamination process. It is safe to use and poses no risk to health, making it an ideal choice for food packaging, เภสัชกรรม, and other applications where safety is a top priority.
- High Functionality: This film offers excellent clarity and brightness, making it an economical choice for laminate with superior visual appeal. It also exhibits high acid resistance and good folding characteristics, making it suitable for write-on or wipe-off applications. นอกจากนี้, it prevents lamination from being pressed, bubbled, and shredding off easily.
- Easy Handling: Once the required temperature and pressure are met, BOPP thermal lamination film is easy to handle and requires no special techniques. This makes it a convenient option for various lamination processes.
Specifications and Applications
BOPP thermal lamination film comes in a range of specifications to cater to different needs. Typically, it has a width of 200mm to 1860mm and a length of 200m to 9000m. The paper core can be either 76mm (3″) or 25.4mm (1″), and the surface tension on both the BOPP and EVA sides meets specific standards.
In terms of applications, BOPP thermal lamination film is widely used in packaging industries, รวมทั้งอาหารด้วย, cigarette, ไวน์, and pharmaceuticals. Its high clarity and durability make it an excellent choice for enhancing the appearance and shelf life of packaged products. นอกจากนี้, it can be customized to meet specific requirements, such as size, ความหนา, and adhesive type.
Lamination Process
The lamination process using BOPP thermal lamination film involves several steps. Firstly, the film is preheated to the required temperature, typically between 80°C and 110°C. แล้ว, it is pressed against the material to be laminated under a pressure range of 5-25 MPa. The lamination speed can vary between 50-60 เมตร/นาที, depending on the specific application and equipment used.
Packaging and Shipping
BOPP thermal lamination film is typically packaged in rolls, with one roll per carton for 3″ paper core and about 20-30 rolls per pallet. The dimensions of the pallet can vary, but commonly used sizes include 1.1*1.1m, 0.90*1.25ม, and 0.95*1.25m. For shipping, approximately 10 pallets can fit into a 20-foot container (weighing about 12,000 kgs), while 20 pallets can fit into a 40-foot container (weighing about 25,500 kgs).
บทสรุป
BOPP thermal lamination film is a high-quality, versatile material that offers numerous advantages for packaging and other applications. Its environmental friendliness, high functionality, and ease of handling make it a popular choice among manufacturers and packagers. With its wide range of specifications and customizable options, BOPP thermal lamination film can meet the diverse needs of various industries, ensuring high-quality results and customer satisfaction.
