Stretch film, LLDPE performance-2

Stretch film, LLDPE performance-2


Stretch film, LLDPE performance - 2

1.stretch film, LLDPE thermal properties.

stretch film, LLDPE melting and crystallization degree, grain size in proportion, so stretch film LLDPE melting point higher than LDPE 10-16, stretch film LLDPE here even the same,

stretch film copolymer monomer carbon number, stretch film higher melting point. This law is also applicable for Vicat softening point. Stretch film heat sealing properties and the

melting of the heat sealing temperature of the corresponding stretch filmLLDPE, heat sealing temperature higher than LDPE 10-16. But stretch film LLDPE than LDPE melting narrower,

so stretch film heat sealing performance is good.

Stretch film LLDPE cold tolerance, on the brittle temperature and melt flow rate of the relations, stretch film LLDPE embrittlement temperature than LDPE, HDPE are low, indicating

that the stretch film LLDPE is resistant to low temperature.

2.Stretch film LLDPE physical and mechanical properties.

stretch film LLDPE tensile performance compared with LDPE, stretch film stretching amount, tensile yield strength, particularly stretch film tensile breaking strength and breaking

elongation, usually available from the stretch film stress-strain curve area derived fracture energy is required, as the resin rigidity index. Very clear stretch film LLDPE good

rigidity, it can be considered as the stretch film LLDPE molecules tethered molecules.

Stretch film rigidity and density relationship: stretch film density is low, less rigid, i.e. more soft. On the same density, the stretch film LLDPE rigidity greater than LDPE. The

use of stretch film LLDPE can be rigid and good film.

Stretch film LLDPE impact strength by copolymerization of a monomer influence, C4 copolymerization monomer copolymer and the impact strength of LDPE is more than C4, C6, C8

copolymerization monomer polymer higher impact strength.

Stretch film LLDPE physical mechanical performance was significantly higher than that of LDPE, stretch film its softness, toughness, cold resistance, durable prick you better than

LDPE.
