Do you know BOPP film?
BOPP film (Bidirectional Focus Polypropylene Film) is produced by stretching a polypropylene film in both the machine direction and the transverse direction.
Why is BOPP film in great demand?
BOPP films are used in a variety of applications including product packaging, labeling and lamination. BOPP film is the recommended substrate for food packaging all over the world because of its basic moisture barrier properties, hermeticity, high quality, visual entertainment as well as shelf appeal, the best opportunity for packaging is single layer/homogeneous structure. For food packaging, it is usually used as a co-extrusion heat-sealing reverse printing film. In labelling, it is favored for its yield advantages (minimum thickness of 0.55 for IML orange peel), recyclability of PP containers, etc. BOPP films are enjoying strong demand across the globe owing to increasing adaptability in the product packaging industry. The benefits of a BOPP transaction are numerous.
What are the advantages of BOPP film?
• Extended service life
Among all other commonly used plastic films, BOPP film has excellent moisture barrier properties and its metallized variant provides a better oxygen barrier to the product. These two properties of BOPP films play a vital role in food packaging, extending the life of items and thus minimizing food waste.
• sustainable development
Compared to other plastic film substrates such as polyester, BOPP films have a considerably lower carbon footprint. BOPP film is the second most popular substrate for flexible food packaging, after cellulose film, due to its environmentally friendly properties. Because of its lower melting point, it requires less power to change from one form to the other. BOPP resin reprocessed pellets are commonly used in the manufacture of injection molded parts, household items such as lounge cushions, chairs, tables, car bumpers, and more.
• Project top quality
In addition to barrier properties, BOPP film has good sealing properties due to its narrow range. Good heat seal strength, low seal initiation temperature levels, wide fixation window, and good machinability provide the food packaging industry with additional advantages to protect food quality.
• Density
BOPP films have unique characteristics among all other commonly used adaptive product packaging films. The reduction in thickness pays off more throughout the conversion process, reducing plastic intake per product. The reduced density allows each roll to be significantly lighter while being the exact same length as another plastic film, allowing for easier material handling.
• Visual/graphics
The excellent openness of clear BOPP films makes packaging items highly visually appealing. In addition, 50% of multicolor tone print jobs can be easily executed on this film for high-quality graphics. In the white opaque film version, the outstanding gloss, high opacity and outstanding brilliance bring an eye-catching effect to product packaging. The range of metallized films offers a superior metallic look to make your merchandise stand out on the shelf. Due to the excellent surface tension, information lamination processes such as foil stamping, UV dispensing and embossing can be performed to improve the visual appearance of product packaging.
