For nearly 100 years, scientific advancements in plastic products have enabled companies to use plastics in a variety of ways to support packaging needs.
Over the years, four of the major types of plastics used for packaging that have been developed are LDPE (Low density polyethylene), BOPP (Biaxially Oriented Polypropylene), PVC (polyvinyl chloride), and PET (Poly Ethylene Terepthalate).
LDPE is a thermoplastic that is widely used for manufacturing various containers, dispensing bottles, wash bottles, tubing, plastic bags for computer components, and various molded laboratory equipment. Its most common use is in plastic bags.
BOPP is a polypropylene film that has been stretched in both the machine and cross directions. BOPP film has become one of the most popular, high growth films in the world, because of its unusual combination of properties: better shrinkage, seals well, twist retention and barrier, transparency, and stiffness. Common uses of BOPP films are potato chip bags, stationary, metalizing, flower sleeves, cable insulation, printing lamination, and many more. It is used in many cases for producing polybags and sleeves.
PVC/PET Shrink Sleeves have their own shrink characteristics and are therefore suited to different applications respectively. The advantage of Shrink sleeve labels that make them a preferred choice is their capability to fit on any bottle shapes and providing highly attractive shelf appeal to the products. PVC Shrink Labels are generally the most cost competitive material, and it is also easiest to control in the shrink process. PET Shrink Labels offer the best scuff resistance and the best shrinkage performance, especially for usual shape of container.
When shopping for the right plastic packaging film, the main concerns are quality and pricing. It takes time to find the right manufacturer who can deliver both.
For instance, Ortega Plasticos (http://b2brazil.com/hotsite/ortegaplasticos), from Brazil, is a top quality manufacturer, renowned in Brazil for producing among the best plastic films. Even better, its prices are unbelievable because not only are they lower than other companies, but the Brazilian currency has devaluated, making its pricing practically unbeatable.
The main product lines include: LDPE (Low density polyethylene) sleeves, BOPP Plastic bags, Plastic packaging iridescent BOPP metallized roll film sheets, Custom BOPP sleeves, and PVC/PET Shrink Sleeves in rolls or pieces.
When you source plastic film, be sure to confirm the quality of the product. If you can match that with a low cost, then these popular products will fly off the shelves. In addition to Ortega Plasticos, you can source your requirements from Brazil by using B2Brazil.com, located at www.B2Brazil.com.
