One of the most important steps related to the production and sale of a product is its packaging. For this reason, companies and factories always try to use quality materials for packaging their goods. Because a good packaging allows manufacturers to transport and store goods more easily. Meanwhile, there are various facilities and methods for packaging, one of the most attractive of which is the use of stretch film.
This special type of nylon has very high elasticity and resistance and is used as stretch packaging in various industries. In the rest of this article, we will talk more about nylon stretch and the difference between manual and machine stretch from the Rata Plast nylon factory.
Stretch film is a type of polymer product that is used to package and secure products. Nylon stretch has very high elasticity and adhesion, and it can be used to fasten the item you want. This type of cover protects the packaged items from environmental damage and does not allow dust to penetrate the product.
The word stretch in this type of film refers to the elasticity of this nylon and is derived from the word stretch. This new method of packaging is affordable in terms of price and it is much easier to use than other old facilities such as wooden or metal logs in packaging.
LLDPE or linear low density polyethylene is the most common material used in the production of stretch film. This polymer material is combined with hexane, octane and butene to produce stretch nylon for packaging. Two substances, octane and hexane, have more carbon and can help the strength of the stretch film. This type of nylon has a very high elasticity and is usually stretched between two and four times its normal size during packaging. This also helps to make the packaged product strong.
Stretch film can be produced in different dimensions and sizes. So, it is possible to customize this product for the packaging of special goods. For example, to produce stretch food packaging, we need raw materials that do not pose a health problem. Because this type of stretch packaging is in direct contact with food. But there are other criteria that should be considered in the production of stretch film. In the following, we will mention a few of them:
Most of the stretch films used for packaging are multi-layered. The number of layers of this nylon can be between one and five. So, instead of wrapping a few extra rounds of stretch film in the packaging, you can choose nylon that suits your work needs. This increases the quality of the packaging and prevents the packed items from moving too much.
One of the important reasons for using stretch packaging is its elasticity and economic efficiency. This makes us need a smaller amount of this nylon to pack a product. Because stretchy nylon stretches to at least three times its normal size and does not tear when stretched. So it can be safely used for packaging.
The thickness of the stretch film depends on the number of layers and can be between 10 and 50 microns. Determining the thickness of the stretch packaging depends on your product. For example, there is no requirement to produce food stretch with a large thickness, because this type of stretch is only used for food storage and is not in contact with environmental conditions.
One of the attractive features that prevent stretch wrapping from shrinking is its adhesiveness. The amount of this adhesion should be such that it surrounds the product and ultimately helps the packaging to be strong.
Stretches are usually produced in transparent form. But depending on the type of your product, you can order stretch packaging in different colors.
A very widely used example of stretch film is cellophane used for food packaging. This nylon cover protects food from dust and increases its shelf life.
Airport stretch
Airports usually use stretch to protect luggage and passenger bags. The amount of packaging goods in airports is very large, and machine stretch wrapping should be used. In addition to keeping the luggage clean, this also prevents them from opening due to sudden movements. Hand stretchers are even used for packing cartons or postal boxes in passenger terminals, because some items are breakable and must be tightly packed.
Stretch can be used to pack heavy pallets in manufacturing plants. The use of two methods of manual stretching and machine stretching for pallet packaging depends on the size of the production center and the volume of the goods to be transported. Because usually small workshops do not have the ability to purchase the necessary equipment and use the manual method for stretch packaging.
Some large agricultural and industrial companies send thousands of tons of goods all over the country every day. So they have to use special devices for stretch packaging. Because in such a situation, packaging must be done at a very high speed and pay attention to the difference in stretch Manual and machine are evident.
One of the attractive features of stretch packaging is to prevent direct sunlight. Farmers and ranchers use this feature of stretch nylons to pack fodder to increase their shelf life.
Another attractive application of stretch nylon is in the packaging of household appliances. Because during moving from one house to another, many household appliances get damaged. But by using stretch nylon, you can pack sofas or other moving items well. This will make your home appliances less damaged while moving home.
Stretch packaging can be divided according to different criteria. According to one of these criteria, stretching is divided into two types, manual stretching and machine stretching. Because stretch wraps are usually produced in rolls and in different sizes. Therefore, for sizes greater than 50 cm, special packaging machines should be used. In the following, we will explain more about the difference between manual and machine stretching.
Packaging of small products can be done manually. In this way of packing, wrap the stretch roll around the package and pull it while twisting. This will make the packaged product stronger. This method of packaging is called stretch hand wrap or manual stretch packaging.
The type of stretch used in the manual method must have the necessary softness and elasticity. Because the tension required for packaging in this method is created by human power and using thick stretch film can be difficult. The speed of doing work in this method is very low and it may not be suitable for packing large pallets. Of course, for the manual method, there are also tools that can be used to hold the stretch roll.
Maybe for packing a limited number of pallets in manufacturing plants, it is possible to use the manual method. But to manually pack more pallets, we need more manpower and time. For this reason, for the packaging of large items, they use special devices that are designed only for this purpose, and it is called a stretch wrap machine. The type of stretch used in these devices is very different and there is no limit to its size. The operation speed of these devices is very high and can significantly speed up the packaging process in large factories.
Choosing the size and number of layers of manual and machine stretch nylons depends on your product. So, in addition to the appropriate width, a stretch film must also have the required thickness. Because instead of using many layers of stretch film, you can use a nylon with the right thickness. Because increasing the number of stretch nylon layers cannot guarantee the quality of your packaging.
Please note that the thickness of manual and machine stretch nylons should be chosen based on the type of product. For example, for misshapen goods with sharp edges, we need a thick nylon. Because this packaging must be able to withstand environmental factors and withstand pressure. The next issue is related to the material of stretch nylon. Because it is possible to customize this product and you can order nylon stretch according to the sensitivities of the desired product.
For example, some stretch films have the property of being anti-electric. This property prevents dust from penetrating your packaging. Therefore, it is quite logical to use stretchy film for food packaging and sensitive goods, which has the property of being anti-electric.
The main difference between hand-wrapped and machine-wrapped stretch film is the width of their rolls. Because small film rolls are usually used in manual packaging. But in machine packaging, stretch rolls with a length of 50 cm to 120 cm are used.
Another difference between manual and machine stretch nylons is related to its users. That is, the manual method is usually implemented for home packaging or in small workshops. But in large production factories and for packing large pallets of tiles or other items, the machine method should be used.
The next issue is related to the cost of using these methods. In the manual method, we do not need a special device and the work speed is low. But in the machine method, special packaging devices must be purchased, which costs a lot, and only large manufacturing companies can afford such equipment for their packaging department. So you noticed that it is very important to know the difference between manual and machine stretching for choosing and using.
When buying stretch film, you should pay attention to several important points. To choose the dimensions of the stretch film according to the product that you intend to package. The next criterion is related to the thickness of stretch nylon, and to determine it accurately, you must consider the appearance of the product and its contact with environmental factors. For example, thick stretch film should be chosen for goods with bad shape and sharp points that can be damaged by environmental factors.
We will need a special type and color of stretch for packing some items such as food. Because this special type of stretch nylon is resistant to ultraviolet rays and helps to preserve food. Usually, the price of the packaging stretch film is determined based on its weight to be This type of nylon has a variety of colors and very high quality, and it must be purchased from reputable centers or sites. Of course, the information presented in this article and the difference between manual and machine stretching can help you to buy the best type of stretch film.
