The following is a display shrink film mainly based on olefin structure.
The simple fact is "At present, there is no industrial technology that can produce biodegradable shrink films in the strictest sense --Refers to the film that is compatible with the market requirements ". The above statement is taken from the literature published by the manufacturer of oxo biodegradable membrane- It must be said that this is not proposed by the manufacturer but by certain distributors of the manufacturer as they are fully compliant with the requirements.
It is necessary to understand some definitions of this particular area.
To put it simply, something that is biodegradable or non-biodegradable is defined above. In short, the EU directive on packaging and packaging waste (94/62/EC)
Defining a package is considered a recoverable requirement. The harmonised standard EN 13432 amplified these requirements in terms of organic recycling and biodegradable packaging.
EN 13432 specifies laboratory testing procedures for the degradation and composite stability and for the determination of the composition of potentially harmful substances in packaging and packaging materials.
Whenever a packaged product is put on the market, it is assessed by using EN 94/62 to meet the requirements of 13432/EC.
Similarly, in short, oxo Biodegradable olefin shrink films do not meet the basic criteria of EN 13432.
Many people think that some attempts are better than doing nothing. Similarly, the products being offered represent a valuable route to greener products.
The fact is that the basic technology is based on special additives that have been in the market for more than 20 years.
Since their first appearance, there has been a lot of doubt about whether these products offer what they promise.
That doubt is still valid today.
To sum up, biodegradable shrink film must be in bacteria or other Micro
As stated in European standard EN 13432, organisms that produce water, carbon dioxide and biomass under natural conditions.
The biomass itself is defined as a biological or organic substance.
Degradation or oxygen degradation materials do not exceed polymers derived from petroleum in a normal way, in which case additives are used to enable them to break down, although the basic molecular structure remains the same.
In this sense, the film is degraded, but there is no change in its chemical composition, so there is no meaningful biological degradation at all.
