Research of the polyethylene packaging layer structure change in contact with a food product at exposure to ultraviolet radiation

open access: yesПищевые системы, 2021
The sanitary and hygienic safety of modern packaging is determined by the layer of packaging material in direct contact with the food product. This layer in most cases is a synthetic polymer of the polyolefin class — low density polyethylene.

The Optical Behavior of Polyethylene Spherulites [PDF]

open access: yes, 1967
Polyethylene was crytallized from the molten film under temperature gradient. As a result, the optically positive spherulites were observed, though only the negative spherulites had been observed previOusly in polyethylene.

Catalytic Hydroxylation of Polyethylenes [PDF]

open access: yesACS Central Science, 2017
Polyolefins account for 60% of global plastic consumption, but many potential applications of polyolefins require that their properties, such as compatibility with polar polymers, adhesion, gas permeability, and surface wetting, be improved. A strategy to overcome these deficiencies would involve the introduction of polar functionalities onto the ...
