Keywords: stretch film, Stretch Film Advantages
Stretch film, also known as wrap film, Heat shrinkable film. PE is the main raw material for film packaging materials, can be hand pull film, can also be used with the automatic winding machine. It has high tensile strength, anti-tear strength and good self-adhesion, so it can wrap the object into a hole, prevent it from falling during transportation, and make the object waterproof, dustproof and anti-damage. What the Heck Is Stretch Film Advantages?
| First, the following is for everyone to introduce the use and characteristics of PE stretching winding film:
A. Packing pallets
Wrap the goods on the pallets to form a whole, to prevent deformation, looseness and collapse in the process of turnover or logistics transportation in the factory; And play a moisture-proof, dust-proof, anti-damage role.
B. The machine drew film packing tray
Carton Packing: the use of wrapped film as a baling film, can protect the carton from the rain while avoiding the courier violence will break the carton inside the loss of scattered items.
C. Machine-made stretch film for packing irregular products
- Machine cover: irregular use of the machine can use winding film wrapped several layers, to prevent the placement of time too long, wet and cause machine rust while playing a dust-proof role.
- Special-shaped product packaging: large-scale special-shaped product packaging can not be customized fixed PE packaging film, then you can use winding film packaging, multi-angle all-round non-corner packaging, to meet your perfect packaging needs.
D. Product surface protection: the winding film has good self-adhesive, but will not form glue residue on the coated object. Can be affixed to glass, building materials, ceramics, doors and windows and another smooth surface, to prevent scratches by a sharp instrument.
| Features of the stretch film:
1. Unitization
This is one of the biggest characteristics of winding film packaging, with the help of the film super-strong winding force and retraction, the product is tightly and fixedly bundled into a unit, so that the scattered pieces become a whole, even in adverse conditions the product is not loose and separated, and there is no sharp edge and viscosity, so as not to cause damage.
2. Primary protection
The surface protection of the product forms a very light and protective appearance around the product, thus achieving the purpose of dust, oil, moisture, water and theft resistance. It is especially important to wrap film packaging to make the packing goods evenly stressed, to avoid the uneven force on the goods caused by damage, which is the traditional packaging methods (banding, packing, tape and so on) can not do.
3. Compression fixity
The product is wound and packed with the help of the retracting force after the stretch film is stretched to form a compact and space-saving unit whole, which makes the pallets of the product tightly wrapped together, the utility model can effectively prevent the products from misplacing and moving each other in the transportation process, and the adjustable tensile force can make the hard products stick tightly and the soft products shrink, especially in the tobacco industry and textile industry has a unique packaging effect.
4. Cost Savings
Using Stretch film for product packaging can effectively reduce the use of cost, using winding film only the original box packaging about 15%, a heat-shrinkable film about 35%, carton packaging about 50%. At the same time can reduce the labor intensity of workers, improve packaging efficiency and packaging grade.
| Application of stretch film
The stretch film is mainly used in conjunction with the pallet, the whole package of scattered goods, instead of small containers. Because it can reduce the cost of transport and packaging of bulk goods by more than 30%, it is widely used in pallet packaging of goods, such as electronics, building materials, chemicals, metal products, auto parts, wires and cables, daily necessities, food, paper and other industries on the integrated packaging of a variety of products;
In the field of warehouse storage, foreign countries also more use stretch-wrap film pallet packaging for three-dimensional storage and transportation, to save space and land.
| The following are the four main stretch film advantages packaging that Sinyar packaging has identified based on customer usage:
- Save on packaging costs
The use of winding film packaging products can effectively reduce the use of cost, the use of winding film is only the original box packaging about 15%, a heat-shrinkable film about 35%, carton packaging about 50%. At the same time can reduce the labor intensity of workers, improve packaging efficiency and packaging grade.
- Good protection
Stretch film around the product to form a very light, protective appearance, so as to achieve dust, oil, moisture, waterproof, anti-theft purposes. The most important thing is that the wrapping film makes the packing goods bear even force and avoid the damage to the goods caused by the uneven force, which is incomparable to the traditional packing methods (binding tape, packing tape, adhesive tape, etc.
- Good fixability
The winding film has super compactness and contractibility, it can bundle the product tightly and fixedly into a unit, make the small parts become a whole, even under the disadvantageous environment, the product is not loose and separate, and there’s no sharp edges or stickiness that could cause damage.
- Beautiful packaging
The product is wound and packed with the help of the retracting force after the winding film is stretched, forming a compact and space-saving unit whole, which makes the pallets of the product tightly wrap together, and can make the hard products stick tightly, so that soft products, especially in the paper and textile industry has a unique packaging effect.
| At present, Sinyar stretch packaging is the thinnest and metallocene can achieve 1 silk, the present formulation of 1.2 filaments is also very mature (already approved and used by the customer)(the thickness of the membrane is also important in the same width and weight, the thinner the film, the longer the number of meters, and the more cost-effective the customer can use it).
Machine winding film is divided into main stretching film and pre-stretching film (now on the market are generally pre-stretching film). Machine winding film thickness is generally 8-15 kg weight of a roll.
Thickness is generally 2.2-3.5 silk, but Sinyar packaging stretch film in order to give customers cost is now developed thin machine film with the thinnest 1.5 silk up.
| To sum up, the application fields of the stretch film are very wide, and many fields have not been involved, and many fields have not been widely used. With the expansion of application fields, the amount of stretch film will increase greatly.
