Production of Stretch Film and Stretch Wrap at Petro Polymer

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

What is Stretch Film?

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

Stretch film is usually produced in different widths and thicknesses and can be applied to packages manually or using specific machines designed for this purpose. The main goal of using stretch film is to preserve and protect the contents of the package and prevent air, contamination, and spoilage from entering.

Industrial Stretch Film

In all manufacturing industries, the last stage of the production process is packaging. The most application and use are in this section for packaging product pallets. However, stretch has many other applications, such as use in food packaging, packaging automotive parts, packaging electronic and electrical products, and more. It is worth mentioning that stretch film, known by the nickname cellophane, is also found in homes and has many applications.

Pallet Stretch Wrap

As the name of this product suggests, this type of stretch is used for packaging product pallets. However, the use of pallet stretch wrap, contrary to its name, is not limited to pallet packaging, and you can use it wherever you feel the need. To perform roll packaging using a manual or machine device, several turns are made around the pallet, 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 products together, making storage and transportation much easier. This type of stretch has slight differences from other types of stretch. Pallet stretch film has a greater thickness and better strength compared to other types. Due to its very low weight, stretch film does not significantly change the weight. Additionally, stretch film, due to its very low thickness, does not alter the size and dimensions of product pallets but rather organizes the products better by gathering and adhering to the pallet. Transparency allows for easy identification of the product, and the product can also be continuously inspected visually.

What Sizes and Thicknesses is Stretch Film Produced In?

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

Width from 30 to 130 centimeters

Length without limitation

Thickness from 30 to 250 microns

Types of Stretch Film Usage

Use of stretch in pallet wrapping (pallet stretch wrap): In large and industrial warehouses and also in large factories, stretch is used for packaging product pallets, which you can see an example of in the photo above.

Use at airports: At airports, before the loading stage on the aircraft, goods are packaged using stretch.

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

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

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

Use in agricultural industries: High thickness and colored stretch are used in packaging fodder and agricultural applications such as covering plants to prevent frostbite. You can see an example of this in the image below, where thick colored stretch film is used for packaging fodder.

Stretch Film or Stretch Wrap?

In the production industry of wraps and packaging films, using the name stretch film is incorrect and should be avoided. The precise name of this product, which has no technical issues, is stretch wrap. However, in this article, to avoid complicating the text, the term stretch has been used instead of stretch wrap.

Price of Stretch Film

The price of stretch film may vary and depends on various factors including the type and quality of the product, size and weight of the order, place of purchase, and more. To be more precise in purchasing stretch film, for price inquiry, you can receive the exact product price 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 depending 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 appropriate thickness has high stretchability, suitable flexibility, and resistance to tearing and breaking.

Elasticity: Stretch film should have suitable elasticity to be effectively applied to packaging and return to its original shape. This feature is important to prevent moisture and contamination from entering the package and to maintain the integrity and safety of the contents.

Adhesion: Stretch film should have suitable adhesive strength to adhere well to the surface of the packaging and maintain the package's integrity. Additionally, it should remain stable after packaging and not separate quickly from the package.

Resistance to tearing and puncturing: Stretch film should have sufficient resistance to tearing, puncturing, and breaking to effectively preserve the packaging and prevent air, dust, and contamination from entering the package.

Transparency: The transparency of stretch film can allow for visibility of the contents inside the package and also provide users with an easy way to check the status of the packaging.

Moreover, paying attention to the type and source of production of stretch film can also significantly affect its quality. Ultimately, to ensure the quality of stretch film, it is better to purchase from reputable and well-known suppliers.
