BOPP Film Uses and Characteristics

1, anti-fog film Food preservation and packaging of fruit thinning air comes with its own water and frozen after the formation of water droplets, easy to form more water droplets in packaging film. "Condensation" creates favorable conditions for rapid reproduction and growth of micro-organisms, especially after the mechanical damage of fruits and vegetables, and anti-fog film is more likely to cause decay.

2, heat sealing film Sealing Film is one of the basic varieties of BOPP film, mainly used for printing, composite bag making or wrapping packaging. It is divided into single-sided heat sealing film and double-sided heat sealing film. Sided sealing film, after the non-heat sealing layer printed pattern, with PE, BOPP, aluminum foil compound bag making for food, tea, beverage packaging. These all require that the film has good heat-sealing properties. Further, with the speed of the packaging also requires BOPP sealing film having high smoothness properties, low temperature instantaneous heat-sealing properties and good heat-sealing strength, to adapt to different types of packaging machine, the film should have a wide heat The sealing temperature range (60 to 135 degree).



3, ultra-thin high matt film With the deepening of reform and opening up and the continuous development of modern technology, people's living standards have been greatly improved, the ordinary packaging has to meet not people living needs, paper and plastic class flexible packaging market demand is growing. In order to meet this requirement, many bopp film manufacturer have developed a variety of new products, BOPP matt film is one of them, it looks like paper like silk, elegant, with good printing, composite performance, low surface gloss, haze, antistatic, easy to fold properties, mainly for books, advertising books, gift bags, paper-plastic composite, can also be used for other substrate composite packaging of food, clothing and crafts. 4 twist Kink packaging for candy, chocolate, beef jerky, preserves, food, instead of not environmentally friendly PVC kink film expensive cellophane packaging. Requirements BOPP film: kink; stiffness, rigid and strong; high gloss; aluminized performance.

5, label film Surrounding label for bottled drinks. Requirements BOPP film: good printing properties, high stiffness, high whiteness, high gloss, low static and smoothness.

6, straw packaging film It is directly used for straw transparent heat seal packaging. BOPP film requirements: good optical performance, the appropriate coefficient of friction and heat-sealing strength.

7, release film Release film is coated with silicone oil used in plaster, protected on the back of the label, silent adhesive tape and other gum products. Requirements BOPP film: thermal dimensional stability; very high; look no defects.

8, isolation protective film It is used in winding forming isolation protection for fishing rods, golf clubs, and other industrial products. Requirements BOPP film: thermal dimensional stability; tensile strength; look no defects.

www.bopp-film.net completed the development of this new film technology product in 2007 and proceeded to commercialize the product to the point where this film technology is proceeding to change the face of film lamination in the world today. This pioneering product development has provided the lamination industry answers for both energy saving, environment-protection, and lower production cost.

Popular Plastic – PE and BOPP

Plastic film is a thin continuous polymeric material. Thicker plastic material is often called a “sheet”. These thin plastic membranes are used to separate areas or volumes, to hold items, to act as barriers, or as printable surfaces. Plastic films are used in a wide variety of applications. These include: packaging, plastic bags, labels, building construction, landscaping, electrical fabrication, photographic film, film stock for movies, video tape, etc.



Materials Almost all plastics can be formed into a thin film. Some of the primary ones are: Polyethylene – The most common plastic film is made of one of the varieties of polyethylene; Low-density polyethylene, Medium-density polyethylene, High-density polyethylene, and linear low-density polyethylene. Polypropylene – Polypropylene can be made a cast film, biaxially oriented film (BOPP), or as a uniaxially oriented film. Polyester – BoPET is a biaxially oriented polyester film Nylon Polyvinyl chloride – film can be with or without a Plasticizer A variety of Bioplastics and Biodegradable plastics are available.

Polyethylene (abbreviated PE) or polythene (IUPAC name polyethene or poly (methylene)) is the most common plastic. The annual production is approximately 80 million metric tons. Its primary use is within packaging (plastic bag, plastic films, geomembranes, containers including bottles, etc.). Many kinds of polyethylene are known, with most having the chemical formula (C2H4) nH2. Thus PE is usually a mixture of similar organic compounds that differ in terms of the value of n. PE film manufacturer said that, one of the main problems of polyethelyne is that without special treatment it is not readily biodegradable, and thus accumulates. In Japan getting rid of plastics in an environmentally friendly way was the major problem discussed until the Fukushima disaster in 2011. It was listed as a $90 billion market for solutions. Since 2008 Japan has rapidly increased the recycling of plastics, but still has a large rate of plastic wrapping which goes to waste.

Biaxially-Oriented Polypropylene (BOPP) films have become a popular high growth film on the world market because of a unique combination of properties such as better shrinkage, stiffness, transparency, sealability, twist retention and barrier (said by BOPP film manufacturer).

BOPP film is used in a variety of applications including: flexible packaging, pressure sensitive tape, printing and lamination, stationary, metallising, flower sleeves, and cable wrap and insulation. Based on a special molecular structure and stabilisation of the resin, these homopolymers provide optimal mechanical and optical properties, as well as excellent processability.

www.bopp-film.net combines to provide more than 20 years of BOPP production, providing its customer the most advanced range of BOPP products in the WORLD today. DECRO currently operates 8 BRUCKNER / MITSUIBISHI / JSW BOPP production lines in its two manufacturing plants in Guangdong Province in Southern China, contributing an annual output in excess of 130,000 tons of BOPP films.
