BOPP refers to Bi-Oriented Polypropylene (BOPP), the output of polypropylene films utilizing an orienting system. BOPP films are produced utilizing a tenter, extended frame consecutive process, or even the double bubble process, where a polypropylene (PP) film is oriented in 2 directions (machine and transverse directions). BOPP films are often used for packaging snacks and candy goods, and multi packs for industrial items.
The primary options that come with BOPP films are high extendible power, enhanced hardness, excellent optics and finest vapor barrier qualities. BOPP films vary from 15 to 50 microns and therefore are most generally fifteen to thirty microns. BOPP films could be single-deck, or co-extruded structures, and clear, non-transparent, or metallized. Furthermore, BOPP films could allow for better gummosity and barrier qualities, treated with acrylic and PVDC films. Homopolymer PP and random copolymer PP are typically used. Here we offer you a large range of thickness and applications available.
Bi-Oriented Polypropylene (BOPP) refers to the manufacture of polypropylene films using an orienting system. BOPP films are manufactured using a tenter frame sequential process or the double bubble process, in which a polypropylene (PP) film is oriented in two directions (machine and transverse directions). BOPP films are typically used for packaging snacks, pasta, and confectionary goods, and as collation wrap for multi-packs.
The main features of BOPP films are improved stiffness, high tensile strength, excellent optics and good water vapor barrier properties. BOPP films range from 15 to 50 microns and are most commonly 15 to 30 microns. BOPP films can be monolayer or co-extruded structures, and transparent, opaque, or metallized. Additionally, BOPP films can be treated with acrylic and PVDC coatings for better sealability and barrier properties. The films use mainly homopolymer PP and random copolymer PP.
