What is biaxially oriented polystyrene?

What is biaxially oriented polystyrene?

1. ”Biaxially oriented” means that the PS film is stretched in two different directions which increases strength and modulus (lower elongation and higher stiffness).

What is oriented polystyrene?

Oriented polystyrene is a durable, flexible, economical material for when crystal-clarity is key. Products made from oriented polystyrene are marked by a “6” within a solid triangle – its resin identification code. Oriented polystyrene starts as a liquid monomer and is transformed into a stable, solid polymer.

What is biaxially oriented?

Biaxial orientation is a process whereby a plastic film or sheet is stretched in such a way that the polymeric chains are oriented parallel to the plane of the film.

What is bops material?

BOPS (Biaxially Oriented Polystyrene) is one of the most popular raw materials currently used in the rigid food packaging industry. The combination of lightweight and high rigidity makes BOPS one of the most efficient materials for use in food packaging.

What is the meaning of biaxially?

(bī-ăk′sē-əl) adj. Having two axes.

Is polystyrene water resistant?

Extruded polystyrene insulation (XPS) is manufactured using a process of extrusion. The closed cell structure of extruded polystyrene (XPS) prevents water penetration to the structure of the insulation board and provides long term strength and durability.

Is biaxially oriented polypropylene toxic?

PP is fully recyclable and can be easily reprocessed into many other products for many different applications. However, unlike paper and other cellulose products, PP is not biodegradable. On the upside, PP waste does not produce toxic or harmful by-products.

Why are oriented films used for packaging?

BOPP films are used in food packaging and are replacing cellophane in applications such as snack and tobacco packaging due to favorable properties and low cost (Fortilene. Oriented films can be used as heat-shrinkable films in shrink-wrap applications or can be heat set to provide dimensional stability.

Does polystyrene burn easily?

Like practically all organic building materials polystyrene foam is combustible. However in practice its burning behaviour depends on the conditions under which it is used, as well as the inherent properties of the material. When installed correctly, expanded polystyrene products do not present an undue fire hazard.

What kind of material is oriented polystyrene?

OPS (Oriented Polystyrene) film is lightweight, durable and strong. Produced by stretching extruded PS film, the material has improved visibility and increased stiffness. Due to being cost-effective and its transparent properties, OPS is most commonly seen in the Graphics / Print and Packaging industries.

What makes Ops different from other polystyrene films?

OPS (Oriented Polystyrene) film is lightweight, durable and strong. Produced by stretching extruded PS film, the material has improved visibility and increased stiffness. OPS (Oriented Polystyrene) film is lightweight, durable and strong. Produced by stretching extruded PS film, the material has improved visibility and increased stiffness.

How is Biaxially Oriented Polypropylene film produced?

Biaxially oriented polypropylene (BOPP) film is film stretched in both machine and transverse directions, producing molecular chain orientation in two directions. BOPP film is produced by a tubular process, in which a tubular

Are there any antioxidants based on polypropylene?

Based on the hydroxylated polypropylene (PP-OH) polymer, a new family of polymeric stabilizers (antioxidants) containing a polypropylene backbone and several phenol groups (PP-HP), with both random and tapered copolymer microstructures, is reported [111].
