Stretch Films Manufacturing
In the roll polymer factory, the production of stretch film is a complex and artistic process that is carried out using advanced equipment and modern technologies. This process leads to the production of stretch film with high quality and superior performance by using high quality raw materials and precise control of film thickness and physical properties.
The first step in the production of stretch film is the preparation of raw materials. These materials include high-quality polyethylene resins that enter the factory in granular form. Then, the raw materials are transferred into the film-making machines in the form of granules in material transfer devices.
In the next step, raw materials are formed into a thin film by high temperature and appropriate pressure. This process is carefully controlled and continues continuously to produce the stretch film with the desired thickness and properties.
Then, the produced stretch films are cut to the desired length and packed in rolls. These rolls are equipped with specific labels and are prepared to be sent to the market.
At every stage of production, in Roll Polymer factory, strict quality control is carried out so that the stretch film produced is compatible with international standards and meets the needs of customers well.

The raw materials used in stretch film generally include polyethylene. These polymers are usually extracted from petroleum sources such as natural gas or crude oil.
Different raw materials such as low density polyethylene (LLDPE) or high carbon polyethylene (HDPE) are used to produce stretch film.These raw materials are mainly used to improve the flexibility, strength and elasticity of stretch film. The use of different raw materials in the production of stretch film can have a direct effect on the final thickness of the film. For example, the use of low density polyethylene (LLDPE) usually gives the stretch film more flexibility and can reduce its final thickness. On the other hand, the use of high-carbon polyethylene (HDPE) may give the stretch film more resistance and strength, which may lead to an increase in its final thickness. Therefore, the type of raw materials used in the production of stretch film can directly affect the thickness and other characteristics of the film.

Frequently asked questions before ordering stretch
How should we use stretch for pallet packaging?
- Pallet preparation: Before packing, make sure the pallet is properly prepared. Ensure that the goods are placed on the pallet in an orderly and horizontal manner and that no part of them falls out of the edge of the pallet.
- Start packing: Start packing by placing the first stretch on the pallet. This will ensure that the stretch is properly attached to the pallet and the packaging will be more secure.
- Stretch wrapping: After the initial placement, gently wrap the stretch around the pallet and adjust as much as possible so that the goods are completely enclosed and there are no gaps.
- Strengthening sensitive points: If there are sensitive or vulnerable points, using stretch to strengthen and stabilize these points is very useful. You can cross the stretch through these points and strengthen the packaging.
- End of packing: After the stretch wrap is completely wrapped around the pallet, close it with tapes or stretch locks and make sure the packing is done safely and tightly.
- Final inspection: Finally, check the packed pallet and make sure that the goods are properly packed and there are no weak points or imperfections.
How do they calculate the price of stretch films and what factors are effective in pricing?
The price of stretch films is usually calculated by manufacturers or suppliers and is influenced by the following factors:
- Raw materials: The type and quality of raw materials used in the production of stretch film is very important. Stretch films are usually produced using polyethylene (PE), but the difference in quality and stability of raw materials can affect the price.
- Film thickness: Film thickness is one of the basic factors in determining the tensile strength and resistance of stretch film. Thicker films usually have a higher price, because they have more resistance and stability.
- The width and length of the film: The dimensions of the stretch film can also affect its price. Films with larger dimensions are usually more expensive.
- Special features: Some stretch films have special features such as anti-UV, waterproof, anti-static, etc., which may increase the price.
- Application: the type of application and purpose of using stretch film can also affect its price. For example, stretch films for food packaging may have a higher price.
- Demand and supply: The rate of demand and supply of stretch films in the market can also be influential. When the demand is greater than the supply, the price usually increases and vice versa.
