The handwrapper is the simplest implement for Conventional Hand-Stretch film wrapping. The film is mounted on a frame where unwinding of the film can be slowed down by turning a handle. This is to allow a certain degree of stretch control. Majority of films are used in the least demanding applications. The handwrapper can also be combined with a turntable driven by an electric motor that is regulated by means of a pedal. Film stretch ratio is less than 100%. Suitable film thickness is 15-20mY and width is 500mm.

Conventional Pre-Stretch film is designed for conventional stretching, and is a technique where the actual stretching is performed between the pallet load and the film roll. The stretch force is generated by the turntable carrying the pallet load. The degree of stretching can be varied by film roll unwinded motion restricted with braking device-centre brake, friction rollers and surface brake. It cannot take advantage of additional stretch in film and is only good for low volume use. Utilizing cost is not critical. Stretch ratio is 100-200%. Suitable film thickness is 20-35mY and width is 500mm.

This means that the film is special formulated and allow to pre-stretched more than 300% before it wound around the load. There are two type of stretching technique that has been developed in the market; Roller Pre-Stretch and Motor Driven Pre-Stretch device.

Roller Pre-Stretch means film stretching takes place between two rollers next to the film roll. The rollers are linked by means of a replaceable gear unit and the degree of stretching can be varied. And the function of Motor Driven Pre-Stretch is in the same manner as Roller Pre-Stretch, but differs in that the stretching rollers are motor driven.

The advantage of using Power Pre-Stretch film is high pre-stretch ratio, load force regulated and suited for irregular loads. Film Thickness: 15-35mY

Conventional Wrapping Film is specifically designed for tray overwrap applications to package fresh food and is particularly suitable for meat, poultry and produce packed on high-speed automatic lines. Used in combination with polyethylene in a conextruded, multilayerpolyolefin-based cast film, provides balanced mechanical properties, good merchantability, optical clarity and excellent elastic recovery. This structure also allows high oxygen transmission rates for optimised product presentation.

Conventional Wrapping Film complies with FDA regulation 21 CFR 175.105 as well as most European regulations when used unmodified and in accordance with good manufacturing practices for food applications.
