Elastic wrapping stretch film roll When choosing the width of different materials of stretch film, in addition to considering general factors such as the size of the packaged items and the packaging method, it is also necessary to consider its own characteristics. The following are the precautions for selecting the width of common materials of stretch film:
PE stretch film
Elastic wrapping stretch film roll Ordinary PE stretch film: The material is soft and has good stretchability. It is generally used for packaging conventional items. For small daily necessities, food, etc., a width of 150mm-300mm can be selected; for packaging medium-sized cartons or parts, a width of 300mm-600mm is more suitable; large pallet cargo is suitable for wide stretch film of more than 600mm.
Elastic wrapping stretch film roll Toughened PE stretch film: It has higher toughness and tear resistance, and is often used for packaging heavier or irregularly shaped items. For building materials, large mechanical parts, etc., it is recommended to choose a toughened PE stretch film with a width of 450mm-900mm, which can better bear the weight of the items and resist external forces to ensure the firmness of the packaging.
PP stretch film
Elastic wrapping stretch film roll Features and applicable scenarios:Elastic wrapping stretch film roll PP stretch film has high transparency and high hardness, but its flexibility is slightly worse than PE stretch film. It is often used for items with high requirements for appearance display and light weight, such as electronic products, gifts, etc. For such items, PP stretch film with a width of 200mm-500mm is more suitable, which can not only clearly display the appearance of the product, but also provide a certain degree of protection.
Special requirements and precautions: Since PP stretch film may break during the stretching process, when packaging some items that need to be tightly wound and stretched to a large extent, be careful to choose the width. If the item requires a large amount of stretching to achieve tight packaging, it is recommended to choose a narrower width, such as 200mm-300mm, so as to better control the stretching strength and reduce the risk of breakage.
PVC stretch film
Industrial heavy-duty plastic film Considering environmental factors: PVC stretch film has good viscosity and flexibility, but its environmental protection is relatively poor. It is still used in some industrial fields that do not have high requirements for environmental protection, such as the packaging of chemical raw materials and hardware accessories. For medium-sized items such as chemical raw material barrels, you can choose a PVC wrapping film with a width of 300mm-600mm; when packaging small hardware accessories, a width of 150mm-300mm is sufficient.
Industrial heavy-duty plastic film Balance between viscosity and width:Industrial heavy-duty plastic film PVC wrapping film has strong viscosity, and this feature should be taken into account when choosing the width. If the surface of the packaged item is relatively smooth and the package does not need to be removed frequently, a narrower width, such as 200mm-300mm, can be appropriately selected to achieve a good packaging effect by using its viscosity; but if the surface of the item is rough or the package needs to be opened multiple times within a certain period of time, in order to avoid damage to the package or difficulty in opening due to excessive viscosity, a slightly wider width, such as 450mm-600mm, can be selected so that the influence of viscosity can be controlled by adjusting the winding method during winding.
