The essential difference between machine-used stretch film and hand-used stretch film is the use of different properties.
Introduction of machine stretch film and manual stretch film:
Hand stretch film
A. Hand stretch film Thickness: 15 Mic-20 mic
B. Hand stretch film Width: 5cm-45CMc, Elongation: 200%-400% D, Colour: degree of transparency
Machine stretch film
A. Machine stretch film Thickness： 20mic-45mic
B. Machine stretch film Width: 45CM-100CMc, Elongation: 300%-500% D, Colour: degree of transparency
The tensile force of machine stretch film is higher, so machine stretch film is thicker than hand stretch film. The elongation of machine-used stretch-wound film is higher, and the puncture resistance of machine-used stretch-wound film is better
Machine stretch film
Machine stretch film needs to be used by the stretch machine, can complete packaging automation, suitable for large volume, use frequency, or high level of automation.
The machine membrane needs high tensile force and high cost and is divided into ordinary type (tensile resistance) and pre-tensile type, the drag type uses the resistance of the product’s own gravity to cooperate with the transformation of the machine chassis to complete the intention of wrapping the object, pre-tension type is the use of machine-made stretch components will be pre-stretched to a certain share of the membrane and then through the chassis of the transformation of the goods.
The tensile force of pre-stretching film is higher than that of non-stretching film and the cost is higher.
Machine stretch film advantages:
There are many advantages in using a machine stretch film, which can prevent dust, moisture, and collapse of goods. Generally, customers who use stretch film have machine stretch film and artificial stretch film, now, the difference between the wrap film and the wrap film. Machine stretch film is the need to wrap film objects placed in the middle of the turntable, through the turntable motor start, driving the turntable rotation, naturally wrapped film evenly in the surface of the object.
At the same time, the elevator motor also starts, driving the stretch film frame to move up and down, so as to achieve the stretch film in the object’s height direction. This has realized the stretch film packaging of the entire surface of the object, which is used by customers with relatively large amounts, it is generally recommended that the use of machine stretch film can reduce the labor force of workers, and machine stretch film is a little tighter than artificial stretch film, using machine stretch film one person can complete all actions.
Manual use stretch film:
The use of hand stretch film is the product will be scattered firmly wrapped into a whole, in order to improve the efficiency of handling, to avoid the occurrence of scattered and loss. Whether it is used for product packing or goods pallet packaging, can achieve a moisture-proof, dust-proof role.
Hand stretch film advantages:
The advantage of using hand stretch film is that it can be operated anywhere at any time. It doesn’t need to move to a certain place to pack.
In terms of price, the machine-used stretch film will be slightly more expensive than hand-used stretch film, machine-used stretch film and hand-used stretch film in the production process is not the same.
