shrink roll

Packaging gives a special character to the product and is one of the important factors in marketing. In addition, one of the most influential issues in product presentation in international markets is paying attention to the way the packaging is designed and the art and creativity used in it, which increases the sales of the product in the target market. Shiring is one of the most widely used types of packaging. Nylon Shiring is a thin, plastic film. When this coating is placed around the product and heated by the Shiring-pack machine, it sticks to the outer wall of the desired product like a nylon pack. In other words, our goal in using Shiring is to apply a layer of transparent plastic Nylon on the products, which in this way we can satisfy customers and consumers in product packaging and also protect them from heat, harmful rays of sunlight, various impacts, dust and scratches.

Nylon Shiring Roll

Usually, Shiring nylon is produced in rolls. These rolls are placed around the product and change shape and Shiring by passing through a heat tunnel at a temperature of about 220 degrees. This product is double-sided and one side is open. Of course, it is also possible to produce Shiring film in a single layer. Shiring nylon film is produced in different thicknesses, each of which is used to package a specific product. The thickness of this nylon varies from 30 microns to 400 microns. In the packaging of industrial products, rolls with higher thickness and opacity are used, and in other cases, transparent and thinner materials are used for greater effect and beauty. The area of ​​​​these films also varies and can be found in the market from about 650 meters up. Usually, the length of these rolls is about 650 meters, 700 meters and 750 meters… and their width is about 10 to 120 centimeters. The weight of each 750-meter roll, 45 centimeters wide and 18 microns thick, is about 17 kilograms.

Shiring film genre

Nylon Shiring is made from plastic materials, the most important of which are:

• Polyolefin (POF): Made from 100% recyclable materials. Its appearance is clear and very shiny. It is suitable for small packaging such as toys and the FDA has approved the use of this material for food.
• Polyethylene (PE): Has high holding power and is used for Shiring large parts. This type of Shiring film can also be printed on.
• PVC: Same as cellophane and is tear-resistant. Used for packaging small products such as raw CD packages and non-food items.

Types of Shiring Film

Types of Shiring rolls include: plain or gut rolls, open side rolls, and single-ply rolls. Here we will briefly explain each of them so that you can understand the differences between these products.

• Simple or gut-shaped Shiring roll: The method of working with gut-shaped or simple rolls is as follows: the consumer cuts the roll to the desired size and, after closing the top and bottom, places the piece into the Shiring machine so that it completely surrounds the product and takes its shape using heat.
• Open side Shiring roll: These rolls are often used in cabin Shiring machines, where the desired product is placed between the rolls from the open side and then inserted into the machine to fix it.
• Single-layer Shiring roll: These rolls are used in two-roll Shiring machines, in such a way that one roll is installed at the top and the other roll at the bottom of the machine, and the piece is placed between the opened sheets and enters the machine.

How to maintain a nylon Shiring roll

• The nylon Shiring roll should be placed horizontally to prevent deformation.
• Store the rolls in a dry place away from moisture and humidity.
• Store at a temperature below 20°C.
• If possible, it should be stored in a covered place so that it is not exposed to direct sunlight.
• A long period of time should not pass between ordering and delivering the nylons and using the Shiring roll so that the cardboard bobbin inside does not deform.
• When using nylons, prevent them from melting too much or burning by adjusting the heat.
• Pay attention to the dimensions of the product you want to package to choose the appropriate width and minimize waste.
