Application Of Bopp Label

1.Ordinary type
BOPP transparent film is also called light film and flat film. Used for printing, BOPP labels, composite (transparent, matting), coating (adhesive tape and PVDC coated film base film), it is the most widely used and most productive type of thin film products; BOPP ordinary film (flat (Film, light film) is suitable for food packaging, paper composite and general packaging printing composite. It is the most widely used variety in BOPP products. It is widely used in various printing and composite products for packaging various foods and articles. In the consumption of light film, the proportion of tape film is large, and its production features are large output, simple process and low technical requirements.
BOPP matte film (matte film) is a kind of plastic matte product with low gloss (gloss less than 15), high haze and diffuse reflection matte effect. It has the characteristics of paper-like appearance, realistic reproduction of colors during printing, and comfortable feel. Matte film is a thin film made by using a matte masterbatch on a single surface and biaxially stretching. The surface of the matte film looks like paper and natural products. It is mainly used for the lamination of books, periodicals, annual report covers, cardboard and other papers. Another use is with polyethylene film, cast polypropylene film (CPP), BOPP film. , Pearl film, metallized film, etc., for various packaging and use. At present, the thickness of the matte film is generally about 12, 15, 18 μm.
BOPP pearl film is white and opaque, has satin-like texture, soft and pleasing pearl luster, low density, excellent flatness, and gas barrier properties. It can be widely used in the direct packaging of dried fruits, ice cream, candy, high-end soap, gifts, etc. At the same time, it is also a good printing substrate, and it is not necessary to perform a full-plate priming when performing surface printing. Therefore, BOPP pearlescent film is very popular. Compared with ordinary BOPP film, BOPP pearl film has three typical characteristics: it presents pearl luster, good light-shielding property (especially obvious to ultraviolet light blocking) and lower density. In particular, the first two characteristics make it enter the high-end market in the packaging field and bring considerable economic benefits to manufacturers.
2.Heat seal type
BOPP heat-sealing film is divided into two types: single-side heat-sealing film and double-side heat-sealing film. It is a polypropylene heat-sealing film (BOPP heat-sealing film) formed by using a heat-sealing master batch in the surface layer and biaxially stretched. For heat-sealed packaging of food, pharmaceuticals and electrical components. BOPP heat-sealing film has both printability and heat-sealability. It is mainly used in compounding, printing, and bag making industries.
BOPP heat-sealable shrink film or PVC heat-sealable shrink film, also known as cigarette film, is suitable for the outer packaging of boxed items such as cigarettes, poker, tapes, mosquito coils, rubber, cosmetics, pharmaceuticals, tea, perfume, gifts and other boxed items. Although the overall usage of BOPP cigarette film is not large, it is the most profitable product in BOPP film. The characteristics of tobacco film production and sales are high technical requirements and high market entry costs.
3.Label anti-counterfeiting film
BOPP label anti-counterfeiting film is used for product labels, advertising printing, books and magazines, bottle labels and overall packaging. BOPP anti-counterfeiting film is made of high-purity BOPP material and special surface layer formula, which can be printed with a laser holographic laser pattern, which can then be directly used for packaging and compounded with paper to make packaging boxes; or used after aluminum plating After packaging, or after aluminizing, it is combined with paper to make a packaging box. BOPP label anti-counterfeiting film is not easy to forge, transparent and easy to identify, and the anti-counterfeiting graphics are clear and easy to distinguish. At the same time, it increases the appearance and aesthetic characteristics of the package, making it applicable to the packaging and anti-counterfeiting of cigarettes, food, pharmaceuticals, and alcohol. Or made into a security label. In recent years, the use of BOPP label anti-counterfeiting film has increased rapidly due to the need for packaging anti-counterfeiting and packaging design.
4.BOPP metallized transfer film
BOPP metallized transfer film is mainly used for vacuum aluminum plating. Traditional gold and silver cardboard are made of aluminized PET film and cardboard. Later, for environmental reasons, transfer technology was developed to make gold and silver cardboard, which is coated with a layer of insulation material on PET. Aluminum plating, and finally the aluminum plating layer on PET is transferred and compounded on the cardboard to form a gold or silver plating layer. The PET film acts as a transfer medium in this process, which is commonly called a transfer film. BOPP transfer film uses BOPP film instead of PET film, because BOPP film is cheaper than PET and does not need to be coated with insulation material during use, saving a process and corresponding materials. The gold and silver cardboard made from the film as the transfer film are consistent in brightness, so a large number of PET transfer films are replaced by BOPP transfer films.
5.BOPP electrical film
BOPP electrical film is mainly used for electronic capacitors and metal capacitors. The technical requirements of BOPP electrical film are very high, and the thickness is required to be 3 ~ 20 μm. With the miniaturization and high performance of components, the amount of films below 6 μm is increasing. Have high dielectric strength, high rollability, thickness uniformity, etc., have special requirements on the production process, also have high requirements on equipment technology, process technology and production operators, but also have very mature experience.
