OPP Film: A New Trend of Food Packaging

In recent years, influenced by international packaging trend, domestic beer and beverage manufacturers start to use plastic film, instead of traditional carton packaging and plastic crate. Among the plastic films, the new type of OPP film is getting popular.

Polypropylene film (OPP film) is pressed of 3 layers of films, adopting steam fumigation craft. It has the advantages of good tightness, better security feature and harmlessness. OPP film is mainly used as labels and the packaging of dessert, candy, soft drink, bread and various kinds of goods. The films are complex, and often have multiple layers. They can be printed and machined. The picture can meet all the needs. And they also can well protect the products in wet and sunny environment.

The European Demand of OPP Film Is Rising

At present, the total production capacity of OPP film in Europe is about 1.045 million tons per year, of which Western Europe’s production capacity is 958,000 tons, accounting for 91.7% of total European production capacity; while Eastern Europe was 8.7 million tons, accounting 8.3% of total European production capacity.
According to statistics of PCI Films Company, world production capacity of OPP film in 2002 was more than 3.8 million tons. The growing demand of OPP film in packaging industry made the world demand rose to 3.17 million tons. Among which Western Europe’s demand is about 823,000 tons, accounting for 26% of total global demand; and in Eastern Europe, the demand is about 8.5 million tons.

Plastic Flexible Packaging Is Popular

In recent years, with the improving of people’s living standards, more and more people focus their eye on plastic packaging safety. According to the statistics, our food packaging has accounted for 60 percent of total plastic packaging.

With the development of materials and processing technology, plastic flexible packaging has played an increasingly important role in many areas. The plastic flexible packaging will become the mainstream of food packaging in the future.

And now OPP film and BOPP plastic film are the first selection of flexible packaging materials. They are colorless, odorless, tasteless, non-toxic, and they have high tensile strength, impact strength, good rigidity and transparency.

In order to get a rapid development of plastic packaging industry, what we must do is to improve the production technology, and reduce the use of raw materials at the same time.

Are Your Plastic Bags Toxic?

Only few people know how to identify whether the plastic bags are toxic, and here are some tips for you to choose a safety plastic bag.

Firstly, non-toxic plastic bag is usually white, transparent or slightly transparent, and uniform in texture; while the toxic plastic bag is always colorful, with poor transparency.

Secondly, shook the plastic bags vigorously, if the sound is clear, it is more likely the non-toxic plastic bag; while it sounds small and stuffy, these bags are largely toxic.

Thirdly, the surface of non-toxic bag is very smooth, and the toxic one is always sticky, hair acerbity and waxy feeling.

If this method is not, then there is a way-by checking the burning flame. The non-toxic bag, like most OPP film, is highly combustible with yellow flame on the top; and the toxic plastic bag is difficult to burn.

All in all, you’d better to buy these products from the formal channels, don’t to covet a cheap and give your body unnecessary damage.

To Get a Better OPP Film

OPP film has many disadvantages: such as it is easy to accumulate static electricity and it has no heat sealing.

When it operate at a high speed production line, OPP film is easier to generate static electricity, so an electrostatic removing device is needed.

In order to get the heat-sealable OPP film, we’d better to coat with the resin solutions like PVD latex, EVA latex etc. and it could also use the method of extrusion coating and co-extruded composite to produce the heat-sealable OPP film.

Of course, different production methods will lead to different results of OPP films.

To get a better performance of films, the multilayer composite method is usually adopted.

Physical Characteristics of OPP Film

Most of today’s OPP film is transparent, and added a small amount of copolymer as auxiliary. Orientation is a characteristic that makes the sealing of the film better. It can prevent from the solvent, water vapor and other types of vapors. The OPP film gives excellent protective properties. Orientation also brings other excellent characteristics to OPP film. Compared with non-stretched film, it brings a better transparency and low temperature flexibility.

Sorts of OPP Film

Pearl OPP:
Pearl OPP film is using polypropylene resin as raw material, mixed with calcium carbonate – CaCO3 and pearlescent pigments and bidirectional stretching later.
OPP film is with silver pearl color, which can reflect more light. The characteristics of gas barrier properties and water resistance are more excellent than other species of BOPP film. 35μm-thicked double-sided heat-sealable BOPP pearlized film can be directly used for ice cream, ice cream and other cold drinks’ packaging.


MAT-OPP is using polypropylene resin as raw material, adding powder matting and so on, bidirectional stretching after mixing. Heat-sealing effect is poorer.

Heat-sealing OPP
the surface is modification treated, and it certainly has sealing effect. It can be divided into double-sided and single-sided.

Something About OPP And BOPP

OPP: Oriented polypropylene (film), stretch ability polypropylene, is one of polypropylenes.
1. Opp tapes: it is the polypropylene film to the substrate, have the advantages of high tensile strength, light weight, non-toxic, odorless, environmentally friendly, and wide use.
2. Opp films and bottles: with the advantages of low cost, portability, and good heat resistance, opp bottle is very suitable for hot filling.
BOPP: biaxial-oriented Polypropylene is an important part of polypropylene. The BOPP films can be divided as follows:
1. The normal bopp film: mainly used in printing, bag making, adhesive tape and other composite substrate.
2 .BOPP hot sealing membrane: mainly used to make bags and print.
3. BOPP Perlized Film: Used for packing food and articles for daily use after printing.
4. BOPP metallized film: Used as the base material of vacuum metallized, radiation, anti-counterfeiting, food packaging.
5.  BOPP anti-fog film: can be used in food packaging, consists of fruits, vegetables, sushi and flowers.

Several Advantages of OPP Film

Opp film industry is a very competitive industry throughout packaging industry. Because Opp film has the characteristics, like unique strength, thin thickness, high transparency and high gloss.

And opp film is good at moisture resistance, and the normal inks could also be allowed to print. This property shows that opp film can be used in many fields.  And it is a good ideal for packaging food, pharmaceuticals, and groceries.

Of course, film is not just only one type, and different films have its different characteristics and its own usage. With coatings like silicone, adhesive, prefabricated film, corona, printing processing, the film could play its different effective role in different scenarios.
