BOPP films (Biaxially Oriented PolyPropylene Films) are produced by stretching polypropylene film in both machine direction and transverse direction. BOPP film is used in vast range of applications comprising packaging, labelling and lamination. BOPP Films are preferred substrate for food packaging globally because of its inherent moisture barrier properties, seal ability, high clarity and graphic reproduction and shelf appeal, best possibilities of the pack being a mono layer/homogeneous structure.
For food packaging, it is prominently used as co-extruded heat sealable reverse printable film. In labeling, it is preferred because of its yield benefit (Lowest density of 0.55 for IML orange peel effect), recyclability with PP containers et al. BOPP Films has a strong demand globally which is driven by expanding flexible packaging industry. The advantages BOPP offers are numerous.
When it comes to plastic packaging, the food industry predominantly uses the BOPP bags or films. BOPP bags are easy to coat, print and laminate, hence making them most suitable for packaging products like snacks, fresh produces and confectioneries. Parallel to BOPP, PP and OPP bags are also available in the market which are used in packaging.
The OPP bags have high tensile strength, and are transparent in colour. These can withstand high temperatures but get wrinkled if used roughly. These are hard to tear and OPP bags are used in the packaging of leather products, clothing, etc.
The BOPP bags are crystal clear polyethylene bags. Their art of manufacture i.e. bi-axially orientation gives them a transparent appearance and this makes them suitable for branding via printing on their surfaces. BOPP bags are largely used for retail packaging
The products inside them can be safeguarded against moisture for a much longer span of time. And that is why these are the most desirable choice in the cloth packaging industry.
