Wells Block – Antiblocks
Blocking is an undesirable attraction between adjacent layers of film or sheet, often making it difficult to the separate individual layers. Certain polymers including, polyolefins and polyesters have an inherent tendency to block.
Blocking can occur during extrusion, conversion processes or during storage. Blocking can reduce packing efficiencies on automated and manual packing lines as it causes for example bags to be more difficult to open and stacks of thermoformed trays harder to separate.
The introduction of an antiblocking agent into a polymer will reduce the blocking tendency allowing films or sheets to be easily separated. The antiblocking agent will create a microscopic roughening of the film or sheet surface which reduces the available contact area between adjacent layers.
There is strong consumer demand for environmentally friendly disposable packaging materials. Compostable materials meet this requirement in many ways. A compostable material will break down completely by biological processes in a time frame consistent with natural materials such as food waste, without leaving any toxic or environmentally damaging residues.
