The main function of Stretch Film is to protect the product stacked on the pallet and prevent the goods from collapsing during the transfer or storage of the pallet as a whole. Often, when the goods are received, the goods appear to be protected with stretch film, and when shipped in bulk, the stretch film is removed. There are mainly two winding methods, one is machine winding and the other is manual winding. These two methods have their own advantages and disadvantages, which need to be selected according to the actual situation.
Our products also iPallet Cover, flexible container bags, also known as tonnage bags or space bags; and Mattress Bag, which are a relatively popular bed core design. Pocket mattresses seal the springs in non-woven bags. The cloth bags are connected by viscose; there is also the Air Cargo Sheet, which is a shipping document issued by the air carrier or its agent; and the Plastic Drop Cloth, which is composed of plastic dots and cloth. Drop plastic. If you want to know more, welcome to consult us, we will serve you wholeheartedly!
If the machine is coated, the action is set in advance, which is relatively standardized. In non-production plants, however, packaging of off-line products often requires the cooperation of forklifts and forklift drivers. It is primarily a forklift that places stacked products on film packs. Manual binding is not easy to standardize because there are many operators, especially the strength of the binding.
For warehouses, stretch film is a non-reusable material. When receiving, please use stretch film for protection. When shipped in bulk, the pull down film needs to be removed from the cargo. Also, if the roll is delivered, it needs to be protected with stretch film. Since stretch film cannot be reused, the cost of stretch film is not a small cost for a warehouse with a large amount of use.
The cost is mainly the purchase cost, minus the income obtained after the waste stretched film is sold as waste, which constitutes the actual cost of the stretched film. Some manufacturers sell by volume (each roll has specifications), some by weight.
First of all, when purchasing, it is recommended to purchase stretch film suppliers according to the annual purchase volume plan, and reduce the price according to the throughput. Or negotiate the step price with the supplier, that is, what is the unit price in the quantity, and what is the unit price after the excess.
Second, the winding method can be optimized. For example, for an unstable stack, three layers are wound, and the stack is relatively stable. Wrap only the top two layers of the pallet to protect each pallet. It can save the amount of stretched film.
Third, for some relatively stable items, buy some reusable "magic tape" to replace stretch film.
Stretch film is an industrial packaging product with strong tensile force, strong ductility, good shrinkage, good self-adhesion, thin texture, softness and high transparency. It can be used to make hand-stretched film wrapping film or machine wrapping film. It can be widely used in the packaging of various commodities. The stretch film has strong puncture resistance and super stretch performance. After the goods are packaged, the goods are more stable, firm and clean, and the waterproof effect is particularly good. Widely used in all walks of life.
Powerful features and benefits of pull-on film:
1. The stretched film is in a constant and stable state at room temperature. After heating, it has a thermal shrinkage effect.
2. The Pet stretch film is polyester, non-toxic and environmentally friendly, and easy to recycle. The new stretch film pre-stretching process makes the original film light and thin, and the physical tensile strength and winding force remain basically unchanged.
The advantages of protective film are:
1. The amount of garbage disposal is reduced. When packaging the same goods, the amount of pre-stretched roll-up film is significantly less than that of pre-stretched roll-up film, so the processing and recycling of the roll-up film is correspondingly reduced.
2. It can be recycled and used together with green winding film, which can not only reduce environmental pollution, but also save the cost of recycling packaging.
3. Reduce atmospheric pollution, reduce transportation energy consumption and exhaust emissions, and reduce costs.
