POWER PE – 100/150/200/300/400 FILMS

Jairam Strap Pvt Ltd manufactures a wide selection of cast stretch film for different applications and machine types. Made from virgin polyethylene and the best raw materials in our advanced Austria-made film casting lines, our films have extreme strength and stretchability.

Power-PE Films concerns the polyethylene, 3-layer, transparent, LLDPE stretch film manufactured with the use of the cast film extrusion machinery.

LLDPE Stretch film is used for packing and protection of products, ranging from loads bundled on pallets to individual items of large overall dimensions.

MECHANICAL PROPERTIES OF STRETCH FILM

Mechanical properties of the stretch film are determined based on tests performed with the use of a device simulating the operation of a wrapping machine in laboratory conditions.

  • – During the Quality assessment, the strength and quality of the film are checked on an assured stretch.
  • – The Ultimate test determines the maximum stretch [%] when the film starts to rupture.
  • – The Puncture test determines the force [kg] needed for puncturing the film
  • – The Retention test determines the maximum force [kg] exerted by the film in reaction to a point pressure.

*Tolerance for mechanical parameters is -5%.

*Maximum stretch of the stretch film is determined in laboratory conditions. The way the film behaves on a wrapping machine depends on individual wrapping machine settings and the type of load being wrapped.

The film maintains its physicochemical properties for up to 6 months when storing the product in the conditions of average yearly insolation of 100 kLy.

It is also possible to manufacture the film of custom thickness after having consulted and confirmed with our Customer Service.

PACKING

The LLDPE stretch film is packed in a manner protecting rolls from mechanical damage and fouling in transport.

The film is wound on a cardboard core, and each core has inside marking in order to facilitate product identification.

Film rolls of width 450 mm and 500 mm are stacked on a pallet vertically, up to three layers high. Each layer is separated with a cardboard spacer and secured with cardboard corner guards.

Each pallet is protected with a rain-proof film hood, wrapped in stretch film and equipped with a label specifying the product.

STORAGE

The Stretch film shall be stored with observance of the following principles:
Rooms used for film storage should be dry and well ventilated.

The temperature of film storage and use: from -50C to +300C.

Maximum relative humidity: 70%.

Up to two full pallets are allowed to be stacked one on top of the other.
