HDPE, LDPE Polyethylene Film
GOST 10354-82 Polyethylene film
Polyethylene film is produced by extrusion of high pressure polyethylene ( HPP/LDPE). It is available in the form of a sleeve, a double-folded sleeve, a folded sleeve, as well as a semi-sleeve and a sheet. Film thickness – from 40 microns to 500 microns, width up to 5000 mm. The introduction of various additives, modifiers and dyes is possible. The range of use of high-pressure polyethylene film is very diverse. Polyethylene film –is an indispensable material in agriculture which is used as an atmospheric coating for greenhouses . The LDPE film is used in the construction and repair of premises. LDPE film protects products from moisture, dust, organic solvents, alkalis and many types of acids. LDPE films are one of the most common types of packaging
LPP / HDPE – low pressure polyethylene (high density).
Products made of it are more durable and tough, the packaging of HDPE shows an increased resistance to stress, tears and sprains. Available in the form of sleeves, folded sleeves, and also in the form of a semi-sleeve and sheet. Film thickness –is from 40 microns to 500 microns, width up to 5000 mm. The introduction of various additives, modifiers and dyes is possible
HDPE film is used:
For packaging of dry industrial and various bulk goods;
For non-oxidizing food products;
For products that need to be cooked in the package;
As an insulating layer in construction, agriculture and other households;
For lamination paper and cardboard.

Notes:
1. It is allowed for films obtained from compositions based on polyethylene
with types of additives p, a, f and polyethylene compositions of recipes 09,
10, 12, 14, 96-100, 901, decrease in tensile strength and relative elongation
at break:
10% for films made on the basis of polyethylene with a melt flow rate of less
than 2 g / 10 min;for 20% for the films made on the basis of polyethylene with
a melt flow rate of 2 g / 10 min and above;
2. The static coefficient
of friction is determined only for a film with a slip agent.
3. The specific surface electrical resistance is determined only for a film
with an antistatic agent.
