Developments And Properties Of Plastic Mimicking Biopolymers For Food Packaging Application, Daniel I. Hefft

Journal of Applied Packaging Research

Sustainability takes an ever increasing importance in the food industry. Here not only the selection of raw materials plays a role, but also packaging materials. Nowadays there is an increasing number of biodegradable and bio-compostable packaging materials available.

However, these materials are still not able to replace mineral oil based packaging materials completely, nevertheless they are becoming increasingly important, since there must be solutions to problems such as pollution of the oceans by plastic waste, growing piles of rubbish from growing population, etc.

The following literature review shows briefly recent developments on plastic mimicking biopolymers, as these materials guarantee great …

The Effect Of Creasing Lines On The Compression Strength Of Adjustable Height Corrugated Boxes, Péter Csavajda, Péter Böröcz, Ákos Mojzes, Bence Molnár

Journal of Applied Packaging Research

Due to its high strength and low density, the corrugated fibreboard (CFB) box is one of the most popular types of packaging all over the world. This packaging device is able to fulfil a huge number of requirements of the logistic process, during the phases of handling, shipping and storage. In addition to this, corrugated packaging is easily machinable, so it is also suitable for special supply chains and products. These special needs include the requirement to fit to the inner measurements of the shipping device, e.g. the shipping container. This is particularly expected in case of less than container-load …

Adding A Polymer Film Barrier Layer In The Press Forming Process Of Paperboard Trays, Ville Leminen, Panu Tanninen, Mika Kainusalmi, Kirubel Bogale, Juha Varis

Journal of Applied Packaging Research

The aim of this paper was to investigate the possibility to add a barrier layer in the press forming phase of paperboard trays by sealing a polymer film to a paperboard substrate. Plastic coating is often an important part of packages manufactured for food packaging. Traditionally the paperboards for food packaging are coated in the paper mill before the actual forming of the package. Experiments with coated and uncoated boards were made and the bonding and adhesion of materials was observed. The results indicate that adhesion between the board and the film can be achieved in the forming process. However …
