BOPP Polypropylene Bags (BOPP = Biaxially Orientated Polypropylene)

What is BOPP?

BOPP stands for biaxially-oriented polypropylene. It’s a variant of polypropylene (PP). It is a thermoplastic, which means its structure will change when heated to specific temperatures – which is what provides it’s heat-seal ability. BOPP is an ideal printing surface and can be made into labels, stickers. packaging and more.

BOPP is oriented with a system that stretches the film in two ( Bi-axial ) directions, specifically the machine and transverse direction during the production process.
For reference - The thickness of plastic films is indicated by Microns ( Um )

What can be packed in BOPP Bags?

What is the difference between Cellophane Bags and BOPP Bags?

Cellophane and BOPP are quite different substrates. BOPP exhibits higher barrier properties over Cellophane.  Cellophane will ( especially with direct exposure to sunlight ) turn yellowish over time, BOPP will not.
BOPP is often thicker and more sturdy with higher tear / burst resistance to that of Cellophane.

What are BOPP Laminate Bags?

A laminate film in some instances is an extruded mix of polymers or a laminated structure – e.g. BOPP / Caste Polypropylene, providing all the properties of our BOPP bags with the added benefit of improved stretch and burst properties. Our Laminate bags have a gusset to enable greater bag expansion and product fill options.  BOPP Laminate offers superior burst strength properties to standard BOPP.
