Production of Stretch Film and Stretch Wrap at Petro Polymer

In this article, we intend to elaborately discuss stretch film, types of stretch film, stretch applications, and more. Stretch film can be regarded as one of the most commonly used plastics in the packaging industry. It can be said that industrial packaging and large warehouses are dependent on the use of stretch film. The reason for this is its numerous features and advantages. Stretch film is commonly known as "cellophane" in the market and among the general public. However, using this name for this product is technically incorrect, and its correct name is stretch film. In the following sections, we will read more about stretch film.

What is Stretch Film?

Stretch film is a type of packaging material produced in a film form. This material is mainly made from nylon polymer and is used for packaging and preserving various products due to its specific properties. Stretch film, because of its high elasticity and flexibility, stretchability, suitable cling, and resistance to tearing and puncturing, is used as an effective solution for packaging and preserving products. Common applications of stretch film include packaging industrial products, food items, household goods, and transporting cargo.

Stretch film is usually produced in a film format with varying widths and thicknesses and can be applied manually or using specialized machines designed for this purpose. The main goal of using stretch film is to preserve and protect the contents of the package and prevent the ingress of air, contaminants, and damage.

Industrial Stretch Film

In all manufacturing industries, the last step of the production process is packaging. The highest usage and application is in this section for packaging product pallets. However, stretch film has many other applications, such as use in the food packaging industry, packaging automobile parts, electronics, and... It is also worth mentioning that stretch film, known by the nickname cellophane, is found in households and has many uses.

Pallet Stretch Film

As the name of this product suggests, this type of stretch film is used for packaging product pallets. However, contrary to its name, the use of pallet stretch film is not limited to pallet packaging, and you can use it anywhere you feel the need. For roll packaging, a few wraps are made around the pallet using either a manual or machine device, covering the entire surface of the product and pallet except for the bottom of the pallet. This is done to protect the product from external factors during transportation and to keep the products together, making storage and movement much easier. This type of stretch film has slight differences compared to other types. Pallet stretch film has greater thickness and better strength than other types. Due to its very low weight, stretch film does not cause any significant change in weight. Additionally, because of its very low thickness, it does not change the size and dimensions of the product pallets, but by gathering and clinging to the pallet, it helps in better organization of the products. Transparency allows easy identification of the product, and the product can also be continuously checked for appearance.

In What Sizes and Thicknesses is Stretch Film Produced?

The dimensions and thickness of stretch film produced at Petro Polymer Rainbow are as follows:

Width from 30 to 130 cm

Length without limitation

Thickness from 30 to 250 microns

Types of Stretch Film Application

Use of stretch film in palletizing (pallet stretch wrap): In large and industrial warehouses as well as in large factories, stretch film is used to package product pallets, as you can see in the picture above.

Use at airports: At airports, before the loading phase onto the aircraft, goods are packaged using stretch film.

Use in production facilities: In various manufacturing facilities such as furniture and table-chair producers, stretch film is used to protect products from external contaminants, dirt, and to safeguard against certain damages like scratches and dents.

Use in food packaging: Stretch film is used to preserve freshness and extend the shelf life of food products.

Household use: Stretch film is commonly used in households for packaging food items. The general public recognizes stretch film by the name “cellophane.” However, the use of this name for stretch film is technically incorrect.

Use in agricultural industries: Stretch film with high thickness and colored types is also used in packaging forage and agricultural uses such as covering plants to prevent frost damage. You can see an example of this in the image below, where thick colored stretch film is used for forage packaging.

Stretch Film or Stretch Wrap?

In the industry of producing wrappers and packaging films, the use of the term stretch film is incorrect and should be avoided. The precise name of this product, which is technically correct, is stretch wrap. However, in this article, the term stretch is used instead of stretch wrap to avoid confusion.

Price of Stretch Film

The price of stretch film may vary and depends on various factors including the type and quality of the product, order size and weight, place of purchase, and more. To be more accurate when purchasing stretch film, you can obtain the exact price of the product as a pro forma invoice after registering and placing an order for stretch film.

Factors Affecting the Quality of Stretch Film

The quality of stretch film varies based on several important factors. Some of these factors include:

Thickness: The thickness of stretch film can have a significant impact on its quality and performance. Stretch film with proper thickness has high stretchability, suitable flexibility, and resistance to tearing and bursting.

Elasticity: Stretch film should have suitable elasticity to apply well on the packaging and return to its original shape. This characteristic is important to prevent moisture and contamination from entering the package and to maintain the integrity and safety of the contents.

Adhesiveness: Stretch film should have adequate adhesive strength to cling well to the surface of the packaging and maintain the integrity of the package. Additionally, it should remain stable after packaging and not separate quickly from the package.

Tear and Puncture Resistance: Stretch film should have sufficient resistance to tearing, puncturing, and bursting to keep the packaging intact and to prevent air, dust, and contaminants from entering the package.

Transparency: The transparency of stretch film allows visibility of the contents inside the package and also provides ease for users to check the packaging condition.

Additionally, considering the type and source of stretch film production can also significantly affect its quality. Finally, to ensure the quality of stretch film, it is advisable to purchase from reputable and well-known suppliers.
