Features and technical advantages of cold stretch packaging

withHeat Shrinkage EquipmentCompare

The cold stretching equipment uses an elastic stretch film with extremely strong clamping force, which can automatically adapt to the size of the goods. In contrast, heat-shrinking equipment uses gas to heat and shrink the film at high temperatures in order to attach it to the product.

Advantages:

Save energy and film

Waste of film is avoided because no gas is used, cold stretching consumes less energy than heat shrinking, and cold stretching requires a smaller film than the size of the cargo, and heat shrinking requires a larger film.

Higher security

Cold stretching does not have any form of combustion, thus avoiding the fire or explosion hazards implied by gas installations.

Greater adaptability.

Cold stretch packaging can use a variety of power sources, such as electrical, hydraulic or pneumatic, heat shrink packaging can only rely on gas to provide heat, electric heating is slower.

Packing beats faster

Cold stretch packaging avoids the preparation stage of heat shrink packaging, and the packaging speed is faster, and the production level of 150 pallets/hour can be reached as soon as possible.

Improved packaging quality

The finished product packaged with cold stretching equipment has a perfect appearance without wrinkles or wrinkles. In addition, because there is no heating process cargo and film will not adhere to each other.

Can adapt to non-heatable products

Similar to fresh vegetables, milk, cooked food, or thermal paper and other products, high temperature will affect product quality. There is no heating process in the cold stretch packaging process, so it is very suitable.

withWinding film equipmentCompare

The cold stretching equipment uses a tubular film to wrap the pallet, and the film will automatically adapt to the goods and protect the 5 sides of the goods. On the other hand, the wrapping film equipment will use more film to package the goods, and it is also necessary to attach a cover on the top of the goods to protect the top of the goods.

Advantages:

Film saving

Cold stretching can save the amount of film used, because the wrapping film packaging equipment needs to be wound repeatedly around the periphery of the goods, and also needs to be capped separately.

Protection from external factors

The cold stretch film is a complete five-sided packaging that provides water tightness and protects the goods from external factors (such as wind, dust, ultraviolet rays, and even moisture, rain and snow).

Transparency and Visibility

Cold stretch packaging because there is only one layer, is completely transparent, can clearly identify the goods brand know and label.

irreparable

Cold stretching requires more than 1000kgf to pull the film apart and set it on the surface of the goods. Any violation of the goods after the packaging is completed is easy to detect, because the film has only one layer and there is no wrinkle or film layer accumulation. Wrapping film packaging can be repaired by hand.

Best packaging quality

In addition to the high transparency of the film, the film bag wrapped on the goods is smooth and smooth, and the surface of the film can also be printed with the company LOGO in advance, which can improve the appearance of the goods.

Faster packaging speed

Fast, cold stretch per hour maximum packaging capacity of up to 200 pallets.

good weather resistance

-20 ℃ to 0 ℃ still has good clamping force and stability, and the clamping force perpendicular to the film direction is significantly improved, so the palletizing stability is good.
