PVC shrink film with the scientific trade name of (Polyvinyl chloride shrink) is placed in the category of thermal cellophanes or thermal nylons, the base of which is PVC or Polyvinyl chloride, which in the production process with The heat and inflation of the film balloon becomes more voluminous and stretched, and later in the product packaging process, by reversing this process by reheating and reducing the area of the film, it causes the product to fit.

Very beautiful and one-handed sewing, smooth surface and Shiny and stretched and very thin thickness makes the product more beautiful and the coating is impervious for durability and product seal, which along with the reasonable price of this shrink roll; This has caused these shrink plastics to become an integral part of the packaging industry, which is used in many industries such as food, automobile, publishing, household plastic appliances, etc.. These packaging cellophanes are used in two ways. And an open side is produced in Neel Film company in thicknesses from 17 to 40 and widths from 15 to 75, which are stretched and shrunk in packaging units by manual, semi-automatic or fully automatic shrinking machines. The final price of the roll PVC sheeting depends on the price of PVC granules, additives and dollars. Due to having the experience and knowledge of polymer and using modern machines, Neil Film has been able to lower the cost of the product for the consumer by producing the highest quality packaging rolls. You can order and buy PV thermal nylons.

An introduction to the industry and polymer science of nylon heat shrinks

Now when you enter a supermarket, you will notice the widespread presence of thin nylons on the products, but if we can only remove all these nylon covers, you will definitely quickly notice the absence of these plastic covers.

The beauty that these products give to the branding of companies along with many other benefits, including the longer shelf life of products; It has made it become an integral part of other industries.

Shrink technique first entered the world of packaging in the 1950s with the raw material polyethylene. Due to its low shrinkability and transparency, as well as the inability to produce thin films with this material, scientists in the field of polymers were looking for a material to overcome this weakness. cover and finally in the early 60s they were able to produce shrink based on polyvinyl chloride.

Production Process

First, the PVC powder, which contains most of the ingredients of the shrink, along with other additives such as stabilizers, etc., is poured into the mixer and mixed well in the mixer with the rotation and heat from friction, and then it enters a container to cool down. and then during the extrusion process that takes place inside the extruder, it becomes a uniform molten material and exits the die in the form of a ring. Due to the heat it has, this balloon is semi-solid and is completely flexible. The tail becomes bigger and more voluminous, and at the end it is wrapped on the bobbins after it has completely cooled down.

The difference between PVC shrink and polyethylene is precisely in its flexibility; Polyethylene does not have the ability to become as thin as PVC, and it also cannot become as bulky as PVC film, which causes PVC to shrink more during packaging.

How are shrink nylons used?

Films that have become more voluminous due to heat and wind are in an unstable state and are looking for an opportunity to return to their previous state and become smaller. This happens when a product is placed between two film layers and first around The nylon around the product is cut and sewn together by a hot electric blade, which is called ultrasonic sewing.

Then hot air is blown to it at about 90 degrees and the nylon returns to its previous volume and area with the help of heat, with the difference that now a product is placed inside it and the film on the product hardens, considering that the Shrink Roll P VC is still warm and flexible, it completely covers all the surfaces of the box or product, and in addition to the elegance and beauty it gives to the product and box, due to the closing of all the pores, it prevents the entry of dust and moisture.

These thermal rolls are fitted on the product by shrink devices, which are produced in 3 manual, semi-automatic and automatic types, which are selected according to the required capacity of the number of packages. Of course, in some cases and without a shrinking device, shrinking can also be done with a hair dryer.

Features of PVC shrink films

The most important features of a good shrink film are high transparency, standard shrinkability, durable and beautiful sewing, resistance to tearing of the film surface due to pressure and sub-zero temperature.

The standard shrinkability makes for even and uniform sewing, as well as the fit of the film on the box or product.

By providing and localizing the most up-to-date machines and relying on the technical and scientific knowledge of the engineers in the research and development department, Neil Film Company has been able to produce standard thermal films, the shrinks produced are of high quality in all the mentioned features. to be

Advantages of shrink PVC

transparency

The inherent transparency of PVC, which is the highest among all polymer coatings, has caused that when it is placed on the package, the product or the package and the design on the

Show it brighter and make the product sparkle, which in turn leads to the beauty of the product and the pleasant feeling of the customers. Also, this transparency makes the product, descriptions and designs on the box better visible.

High shrinkability and perfect fit on the product

In addition to the transparency, as mentioned above, due to the high flexibility of the PVC shrink and the high shrinkability of this product, there is a reason to completely stretch the thermal cellophane on the package and fit the product.

Beautiful, uniform and level ultrasonic sewing

  This feature, along with high transparency and uniform and level sewing, gives more beauty to the shrink products.

Transparency, beautiful sewing and fitting on the product and subsequently the beauty of the shrunken products; Shrink PVC has become an important tool for companies for branding and more sales.

impenetrability

  PVC film, in addition to uniform stitching, makes nylon impervious and air and moisture cannot have a direct relationship with the product and cause the product to last longer, especially food and health products.

Tear resistance

The high resistance of these rolls against tearing, as well as the ability of Neil Film Company to produce various thicknesses, has made them have special strength against sharp surfaces and is suitable for any type of packaging.

The polished surface of the PVC shrink when placed on the product package makes it easy and complete to clean when the dust settles on the product, which makes cleaning easier and faster, especially in stores due to the large number of products on the shelf. becomes

The use of thermal PVC cellophanes

According to the advantages of these nylons, they are mostly used in places where the purpose is: branding, more durability, promotion, seals, etc.

In which industries are PVC shrinks used?

  These shrinks are mostly used in the food industry for packing biscuits, chocolates, traditional sweets of different cities, food chains, food powders, etc., electronic and electrical industries, publishing, toys, automobiles and lubricants, plastic products. Kitchen and home of many other industries.

Price and purchase of PVC shrink

The final price of pvc sheeting roll depends on the price of PVC granule, other additives and also the dollar rate, and due to having the experience and knowledge of polymer and having the latest machines in the world, Neel Film has been able to produce the highest quality packaging rolls, the cost of goods to lower the cost for the consumer.
