BOPP PACKAGING FILMS
In today’s life, BOPP membranes are widely used. You may not have noticed, but there are many items made from this membrane. Typical examples are cargo bags, soft packaging for food, etc. So what is BOPP film? What is the application of this membrane and what are the outstanding properties? Let’s explore through the following shares to use this material in the most optimal way.
What Is BOPP Membrane?
BOPP film, also known by its English name, is Biaxial Oriented Polypropylene. This is a kind of plastic film, produced from PP (Polypropylene) plastic beads.
This type of plastic is harder than PE and is considered to have the general characteristics of good tensile strength, higher transparency than the above plastic. Besides, BOPP film is also known as a thin film, with a thickness of 10 ~ 40 microns. The reason is due to the low density of PP particles, only 0.90 g/m3.
However, this type of network has a higher strength, so it is widely used. You will see them used a lot as thin films, with relative stiffness and high transparency.
The BOPP film is OPP oriented, which means it can be stretched in 1 or 2 directions. This is the way to get strong force along with higher hardness and crystallinity.
BOPP plastic film has the ability to effectively prevent odors of all kinds. Moreover, using this type of plastic film has a very good anti-mold effect. You also avoid the risk of dirt getting on your items by wrapping the product with BOPP film.

Types of BOPP films:
Currently, there are two types of BOPP plastic film, called clear (glossy) BOPP film and translucent BOPP film. The thickness of these two types of films is from 12 to 40 µm (micrometer).
Usually, both of these plastic films are used in companies specializing in printing, after printing, using lamination on soft packaging for products. For example, instant noodles, confectionery, coffee bags, cereals, all kinds of paper packaging, carton packaging or for leaflets, catalogs, book covers, magazines, picture books, picture books …
Glossy BOPP film
Glossy BOPP film is also known as water glue film, clear BOPP film, water bubble film. This is a type of film without glue, which is released into the finished product before being passed through the drying batch for pressing, mainly used for printing.
They are used to laminate very thinly to the surface of the printed paper. Their purpose is to create a beautiful shine, waterproof and protect the surface of the printed paper from scratches, or mold.
The implementation process consists of coating the surface of the printed paper with a layer of liquid glue (water glue). Then lamination with BOPP plastic film to create gloss, moisture resistance, water resistance and increased durability.
The advantages of this type of film are that it is only necessary to invest in a cheap BOPP laminating machine, use easy-to-find materials, and fast laminating speed. In addition, the finished product cost is not high.
However, the disadvantage of water-balloon BOPP film is that it can cause environmental pollution if bad glue is used, which does not guarantee quality. Besides, it is necessary to wait for drying if there is no dryer, and it also consumes the membrane discharge capacity.
Matte BOPP film
Translucent BOPP film is a type of film that when rolled onto the surface will create a translucent, not completely transparent. The surface of this film is moderately smooth. This is the type of film used in companies specializing in laminating for soft packaging of food, instant noodles, confectionery, coffee, ….
This type of film is coated with an additional layer of EVA glue or certain chemicals. The manufacturer will use a thermal laminating machine to melt the pre-coated glue on the surface of the film to stick to the surface of the paper or printed board.
The use effect of this type of BOPP film is to increase gloss, effective durability. At the same time, it also has the effect of anti-mold, waterproof, anti-dirt and some types of bacteria
Application of BOPP Film:
Because BOPP membranes are cheap, possessing many beneficial properties, they are widely used. There are many different fields as well as different appliances that use this type of plastic film. Typical examples are:
- Lamination: used to wrap the surface of brands or cover books, magazines, picture books, picture books …
- Lamination for items such as catalogs, flyers, Brochure, Namecard or Poster paper, etc.
- Soft packaging for food: instant noodles, confectionery, coffee, cereal powder packets….
- Used as packing tape.
- Used as a shopping bag.
- Wrapping around cigarette packs, glass wrapping flowers…
With its advantages, BOPP film is widely applied in life. There are many objects around us that are preserved and kept in quality by using BOPP thin film. However, it is recommended to use BOPP film produced with guaranteed quality, to avoid toxicity as well as the risk of environmental pollution.
