Detail of Coated Bopp Films and their Application

Plastic film is a film formed from a thin continuous polymeric material. If the material is thicker it is called as sheet. All the varieties of plastics are easily converted into a thin sheet. The polypropylene can be converted into a uniaxial or biaxial cast film. This is commonly called as BOPP (Biaxial Oriented Poly Propylene). The coated film is a polypropylene film that has been stretched in the machine in both the directions. This film has gained wide acceptance and is considered as a high growth film. It is considered as a substitute for wax paper, aluminium foil and waxed paper. BOPP film is made in four simple steps:

1.      Co- extrusion process.

2.      Orientation of film in two directions

3.      Primary slitting of BOPP film

4.      Secondary slitting or metallization

The main features of BOPP films are:

1.      It provides an excellent clarity for a clear view.

2.      It has good dimensional stability and flatness.

3.      There is a low electrostatic charge.

4.      It acts as an excellent barrier to water vapour.

5.      It has a high gloss.

6.      It shows a good performance on high speed printing.

7.      It acts as an excellent resistance to the oils and greases.

8.      It shows a great resistance over various temperature ranges.

9.      It is not affected by moisture.

10. The shrinkage of the plastic film is low.

11. The recyclability of the film makes it worth using again and again.

 

Uses of BOPP Films

 

Due to the features and qualities offered by the BOPP films it is used in the following industries

 

1.      Food and Beverage packaging

It provides an excellent combination of the function and quality films. It blocks moisture and entry of microbes in the food. One can create coloured films form it to cover the food. The colourful packaging acts as an attractor for the buyers.

 

2.      Medical packaging

It helps to prevent the microbial growth in the medical device packaging which may include bed and surgical trays, IV stands and medical carts. The devices can be protected from contamination from air borne contaminants.

 

3.      Personal care product packaging

The film finds its use in the cosmetics, hair care, eye care and infant care products. They help to prevent the products from the outside contamination and microbes.

 

4.      Tamper evident packaging

It is used in packaging of adhesive which are pressure sensitive. They are used in labels and seals.
