Glossary


E

Elasticity
The tendency of a body to return to its original shape after it has been stretched or compressed

Embossing
Pressing a raised pattern into a bag to increase the ease of opening and handling

ESD
(acronym) Electro-static Discharge.

Ethylene
A colorless gaseous aldene obtained from petroleum and natural gas and used in manufacturing the most common plastic bags.

EVA
Ethylene-Vinyl Acetate copolymer is an additive. Much softer and clearer than LDPE or LLDPE and has lower melt temperature. Its melt temperature goes down, while its softness increases with increasing vinyl acetate (VA) content. EVA resins with 2-18% VA content are used for cast and blown packaging films.

Extrusion
One of the most common plastics processing techniques covering a vast range of applications in which resins are melted, heated and pumped for processing. Extrusion machines accomplish these tasks by means of one or more internal screws. In extrusion, the material to be processed is sheared between the root of the screw and the wall of the barrel that surrounds it. This process produces frictional energy that heats and melts the substance as it is conveyed down the barrel. Melted extrudate from the machine is further processed after the extrusion phase, which typically produces pellets, sheet, cast film, blown film, fibers, coatings, pipes, profiles or molded parts.
