LLDPE Stretch Film

1. Product introduction

Stretch film is a film material widely used in product packaging and protection. It has excellent protection performance, can effectively protect the product from the external environment, while having high flexibility, can adapt to a variety of shapes and sizes of products. In addition, since stretch film is usually transparent or translucent, it also provides good visibility for supply chain management and inventory management. In terms of cost effectiveness, stretch film usually has a lower cost than other alternative products and is an affordable packaging material. Mechanical stretch film is a packaging material with many advantages, it is excellent in terms of protection, flexibility, visibility and cost effectiveness. When choosing stretch film products, customers can consider the use of hand stretch film and machine stretch film two different products according to their own operating conditions.

2, the difference between hand stretch film and machine stretch film: Generally speaking, the stretch film on the market is divided into two kinds: machine stretch film and hand stretch film. The use effect of these two stretch films is very different from the name, so when you buy film products, you must distinguish between these two products.

1) The machine stretch film is to place the object to be wrapped in the middle of the turntable. By starting the turntable motor, the turntable is driven to rotate, and the film is naturally and evenly wrapped on the surface of the object. At the same time, the lifting motor is also started to drive the stretched film frame to move up and down, so as to achieve the stretched film in the direction of the height of the object, so as to achieve the packaging of the entire surface of the object, which is more suitable for large packaging users. The machine stretch film is dense and reduces labor costs.

2) The hand stretch film is to securely wrap the dispersed product together to improve processing efficiency and avoid dispersion and loss. This packaging is simple stretch film packaging, the stretch film is mounted on a shelf or handheld, and the tray rotates or the stretch film rotates around the tray. The packaging speed is slow, and the appropriate film thickness is 15-20μm.

Therefore, in general, the requirements of these two stretch films are different, and the usage is also different. In the production of machine stretch film, polypropylene is mixed with metallocene, so machine film is more expensive than hand film. Therefore, when we buy, we must choose according to their own working conditions

3, The use of stretch film：It is widely used in goods pallet packaging, can be used in electronics, building materials, chemical, metal products, auto parts, wire and cable, daily necessities, food, paper and other industries of packaging. In the field of warehouse storage, it is also possible to use stretch film pallet packaging for three-dimensional storage to save space and occupy an area.

4, How to use the stretch film：Stretch film packaging must be stretched, there are two forms: direct stretching and pre-stretching. Direct stretching is to complete the stretching between the tray and the membrane. This method has a low tensile ratio, which may lead to the reduction of the membrane width, the loss of puncture performance, and the membrane is easy to break. The tensile ratio of pre-drawing can reach more than 300%, which saves the material cost correspondingly, and thus has a higher cost performance.

6. The application field of stretch film：The application field of stretch film is very wide, it can be used for a variety of goods concentrated packaging. In the logistics industry, for example, it can help protect products, reduce labor and improve efficiency. In addition, it can also be used in the food field, because it is an environmentally friendly recyclable material, odorless, colorless, and can be directly packaged food.
