Biaxially Oriented PolyPropylene (BOPP Film) is the film that has been stretched both mechanically and also in manually using cross direction technique. Due to its advantages this film has become one of the most popular and highly demanded films all across the globe.
These are the films that have BOPP as the base material. Its unique attributes are:
1.These films have the density nearer to 0.90 g/m and hence it renders high yield at the same cost as compared to other films viz. polyester films
2.BOPP films have excellent gloss and high transparency that give it an excellent look and fine finish.
3.Other polyester films are not resistant to outside pollution whereas BOPP films act as good moisture resistant barrier and have tendency to resist pollution and harmful chemicals.
4.This film have spectrum of wide range and are easily available viz. Matte, Glossy, Silky matter etc.
5.Excellent clarity
6.Best dimensional stability and flatness
7.Low electro static charge
8.Acts as good barrier to water vapor
9.BOPP films exert good and optimum performance on high speeding printing
10.Apart from resistant to harmful chemicals and pollution, these films act as resistant to oils and grease
11.Good puncture and flex crack resistance over wide range of temperatures
12.Also BOPP films are not affected by the moisture and does not wrinkle or shrink with changes in the environment
13.They are recyclable
BOPP films have great benefits like:
They are environment friendly
Are light in weight
Are accepted easily all across the world
Damage of the product due to transport, weather etc are reduced to great extent
Has the tendency to keep the product dry
No de- lamination is required
They have good clarity and are resistant to ultra violet rays
BOPP films have wide range of applications:
1.Grade F1 films are used for packing of food and their sealin
2.Standard BOPP films are used for electrical applications, printing and lamination
3.Text book covering
4.Other applications includes extrusion coating, flower packing, reverse printing and lamination
5.They are also used as adhesive tapes and pressure sensitive tapes
6.White and opaque colored film are used for general purposes like printing pouching, cable over wrap, strip packaging for cough drops and heat sealable BOPP films are used for general purpose and over wrapping.
