What are the types of stretch film or nylon fodder packaging?

The use of stretch film is very common in the packaging and transportation industry. There are different types of stretch film, each of which has its own characteristics and uses.
1. Machine stretch roll: This type of stretch roll is designed for use in automatic packaging machines. It offers high twisting capacity, high speed and more efficiency in packing fodder and other materials.
2. Manual stretch roll: This type of stretch roll is designed for manual use. Suitable for packing the smallest items, it weighs less and is usually used for travel and temporary use.
3. VCI roll stretch: This type of roll stretch has anti-rust and anti-corrosion properties. By breaking down harmful substances, it protects tools and machinery against moisture damage and oxidation.
4. Air stretch roll: This type of roll stretch has the ability to stretch in the length and width of the movement, and it is wrapped in a homogeneous and high strength form using an air fan. It is suitable for packing large and bulky objects.
5. Roll stretch UVI: This type of roll stretch protects against all sun damage and heat intensification by using univisibility-light. Therefore, it has a longer lifespan and is used more outdoors.
6. Reinforced stretch roll: This type of stretch roll is created with reinforced layers that give more strength and strength to the film. Therefore, it has the ability to pack and transport heavy and perishable loads.
Another type of stretch has four types in terms of resistance, transparency and benefits:
1- cast stretch silage (Cast Stretch)
Stretch silage is cast type. This type of stretch silage is made using extrusion technology, also known as CAST. Using this method of producing stretch film increases the clarity and brightness of the film, and as a result, the objects inside it become visible. Also, this production method arranges the molecules in the stretch silage in such a way that the film is naturally more stretchable and flexible.
2- What is blown stretch roll? By what process is it produced?
Blown stretch roll is a type of packaging film that is used to package and protect products. The inherent property of this type of film is its flexibility and complexity. This type of packaging film is made of high quality plastic and can be applied manually or using packaging machines. Compared to the blown stretch of other clustering, it has the highest degree of strength.
Blown stretch roll is a type of polymer film that is produced using the blown extrusion process. In this process, polymeric materials such as polyethylene are heated and remelted from a mold and then formed into a thin film.
The final blown roll stretch film has high stability and greater physical strength due to its special production process. This high strength makes the blown stretch roll fit well on the objects and cover the objects well. Also, the greater strength of the blown stretch roll makes shocks and pressure better absorbed and prevents the objects inside the blown stretch roll from being hit.
Although the blown stretch roll has more resistance than other films, it has less transparency and its price is also considered as one of the simpler stretch films due to its high properties.
3- Pre-stretched film (PRE Stretched)
Pre-stretched film (PRE Stretched) is a type of packaging film that is stretched in a special way before using it in the production process. Using this type of film for fodder packaging or any other type of packaging is very suitable because of its special features.
By drawing this film before use, you will enjoy a series of advantages. First, using pre-stretched film saves time and money because there is no need to adjust the stretch of the film before packaging. Therefore, packing can be done more quickly.
Second, the use of pre-stretched film reduces packaging loss during shipping. Due to the smaller size of the film cells and its high tensile strength, a tighter packaging is obtained, which prevents movement, damage and contamination of the goods.
Also, this type of film has more stable elasticity, which helps to stabilize the packaging better and prevent the packaging film sheets from falling. As a result, your packaging will remain stable over time.
In general, the use of pre-stretched film increases the quality and effectiveness of packaging and is done with less cost and time.
Stretch film is a new technology that is used for wrapping and packaging products. Unlike regular stretch films that need to be stretched using a machine or a lot of hands, pre-stretched stretch film is already stretched and does not need to be stretched further.
To use pre-stretched film, you must first place the roll of film on your product and then tighten the film and wrap it using special tools and machines that exist for this purpose.
The importance of using pre-stretched film is to reduce costs and save film consumption. Also, unlike conventional stretch films that can cause product bending, pre-stretched film maintains product shape and transports products with minimal loss.
4- Color stretch roll
Colored stretch roll is a type of plastic film that is used for packaging and guaranteeing the trust of goods. These rolls are designed and manufactured in such a way that they have high resistance against holes and tears and provide sufficient protection for the items inside them.
To produce colored stretch rolls, raw materials such as polyethylene, polypropylene or PVC are needed first. These materials are then converted into plastic films by methods such as spinning, extrusion or nylonization.
Then, the desired color is added to the plastic film to turn it into a specific color. In addition, if necessary, additives such as protective layers or materials resistant to heat and wear are also added.
Finally, these color films are formed into rolls and are ready for use. The colored stretch roll is designed with emphasis on high resistance and flexibility so that it can be used for bulky or easily broken packages.
Because colored stretch rolls are made of high strength materials, they are usually recyclable and used as a sustainable option in product packaging.
How to choose a roll of stretch film?
When choosing a stretch roll, some important factors are:
1- Load weight: It is very important to check the weight of the load you plan to put on the stretch roll. Each roll has a maximum weight that it can support, so you must make sure that the selected roll can support the weight of your load and withstand it well for a long time.
2- The shape of the load: the shape and size of the load also have a great effect on the choice of stretch roll. Depending on the shape of the load, you can use stretch rolls with different thicknesses. Consult with your supplier if you need to select a specific stretch roll.
3- Loading force: You should pay attention to the fact that the amount of force applied to the stretch roll is different according to the way of loading and carrying the load. Divided loads placed on the stretch roll may introduce a variety of vertical, horizontal and tensile forces to the roll. Therefore, you should choose the stretch roll based on its strengths.
4- How to maintain the stretch roll: You should pay attention to the long-term storage ability of the stretch roll and its resistance to external factors in order to make the right choice. For example, if you have your stretch roll in harsh environments (such as very cold or hot temperatures), you should use an industrial grade stretch.
According to these factors and in cooperation with the stretch roll supplier, you can choose the right stretch roll for your needs.
