This document summarizes information about the use of ethylene vinyl alcohol copolymer (EVOH) in flexible packaging applications. It discusses Kuraray as the world's largest producer of EVOH, the properties and processing of EVOH, and various applications where EVOH is used as an oxygen and aroma barrier material, such as packaging for milk, sauces, bag-in-box wines, laminated tubes, snack foods, agricultural films, and hermetic storage bags. Emerging uses of EVOH include replacement of glass, metal, and aluminum foil in packaging through its barrier properties and ability to provide recyclable packaging structures.

I recently retrieved this presentation on extrusion coating and lamination from more than 20 years ago.
Until 1998 BASF was organizing a film seminar combining classroom and practical training. I was working as a film service technician and application developer at Fos-sur-Mer, a former Shell site in southern France, where two high-pressure autoclave reactors were producing mainly extrusion coating and special blown film LDPE grades. I was at the time also the company's global extrusion coating expert when BASF and SHELL had decided to divest their polyethylene activities in a common subsidiary they branded ELENAC (that later merged with TARGOR to become Basell, which itself later acquired Lyondell to give birth to Lyondellbasell) until it was decided to exit from extrusion coating activities and sometime later to shut down the production of LDPE with autoclave reactors that had become uneconomical to operate. This presentation represents the apex of one year on my implication in extrusion coating and the first and last time I had the opportunity to present it during the last film seminar session ever taking place for german customers. After that the seminar was cancelled and never had I a chance to make an english version. The slides are mostly self-explaining and little has changed as well on the fundamental concepts of extrusion-coating and extrusion-lamination.
Plastic films are used to wrap food related items like, candy, snacks, nutritional bars & powders. This presentation explains the different types of packaging films and the equipment used to wrap the films.

Benefits And Applications of PET Plastic Packagingplasticingenuity
Polyethylene terephthalate or PET, is a staple in food and beverage packaging. It's also used in the packaging of plenty of other products, though not necessarily ones you want to eat or drink—PET is a mainstay for packaging things like cosmetics and cleaning chemicals. Just look at the recycling code on any PET plastic package, and you'll see: It's number one. Learn the benefits and applications of PET from the industry experts at Plastic Ingenuity.

High-barrier packaging can significantly reduce absorption, desorption and diffusion of gases and liquids to maintain the quality of food. This paper provides technical information on the barrier properties of a new solution based on a passive non-nanosized technology for its use in polyolefin materials. This is interestingly presented as a novel alternative to other new commercial passive fillers such as unmodified or organically modified nanoclays. In particular, the new additive offered better barrier performance during sterilization conditions, in which the water vapor permeability was reduced to about 60% when compared to the unfilled polypropylene film.
Ferro, a leading supplier of specialty plastics, has recently developed OPTUM® Barrier masterbatch for a wide range of polymers. This can be incorporated by melt processing in most of the manufacturing processes involved in the developing of single and multi-layer structures in flexible and rigid packaging. In particular this is suitable for food packaging applications in order to increase product protection and shelf-life. Barrier applications can be found, however, in other market segments such as cosmetics, industrial containers and agricultural films, where barrier to oxygen and other gases is also critical.

Plastic waste management- Conventional and New Technologyrmeena99
Plastic is a material consisting of any of a wide range of synthetic or semi-synthetic organic compounds that are malleable and can be molded into solid objects. Plastics are typically organic polymers of high molecular mass, but they often contain other substances. They are usually synthetic, most commonly derived from petrochemicals, but many are made from renewable materials such as polylactic acid from corn or cellulosics from cotton linters.Plasticity is the general property of all materials that are able to irreversibly deform without breaking, but this occurs to such a degree with this class of moldable polymers that their name is an emphasis on this ability.
