Stretch film is a highly flexible plastic film used for wrapping and securing products during storage and transportation. It is made from linear low-density polyethylene (LLDPE) through a process called blown extrusion. This film is extensively used in warehouses and industries to strengthen bundles, eliminating damage, scratches, and contamination.
15-micron stretch film comes in various types, including hand, machine, and colored, to fit specific wrapping needs.
Hand stretch film
Hand stretch film is an ideal solution for packaging loads of different sizes. Typically available in rolls that weigh between 1 kg and 2 kg, this film is very popular for manual wrapping. The thickness is usually around 10 to 15 microns.
Machine stretch film
Machine or automatic stretch films are much thinner and tougher compared to hand stretch films. This makes them suitable for use in machines. They are more delicate and help secure and stabilize pallet loads. This type of film generally comes in thicknesses starting from 9 microns up to approximately 35 microns.
Colored stretch film
Colored stretch film is majorly used for theft prevention, product display, and in situations where opaque packaging is needed. This film is normally available in a range of colors, including blue, black, white, and green, among others. Usually, the thickness of colored pallet shrink wrap films is around 15 μm.
Vented stretch film
The vented stretch film is an exceptional choice for industries that deal with food products. The film incorporates small perforations that allow air to pass through to reduce moisture buildup as well as spoilage. This film is available in various thicknesses, generally ranging from 10 to 20 microns.
Pre-stretched film
Pre-stretched film is one of the most rigid stretch films. It is initially stretched before it is wound onto a pallet. When fully utilized, this type of film minimizes the extension available, thus securing a constrained load. Pre-stretched film standards come in thicknesses of about 12 to 20 microns.
The primary design aspect of stretch film is determined by the amount of stretching that can be achieved and the film's thickness, which among other things, determines its tensile strength and elasticity. A clear shrink mulch plastic film may come in different formats for specific uses.
Omni-directional wrapping
The omni-directional wrapping design allows for movement in all directions. This means the film can be wrapped around the load in any direction without having to worry about tearing. This property makes it possible for loads to be tightly wrapped, boosting stability and security, an important requirement especially during transportation and storage. Typically, this kind of film is important in sectors where premium pasting strength and security are mandatory.
Star pattern design
The star pattern design lets the user stretch the film even more at particular angles, which improves load stability by creating tension in every necessary direction. The design ensures that the film clings onto itself securely, eliminating the chances of the film losing its grip mid-transport.
High puncture resistance
Film films with 15 μm thicknesses depend heavily on high puncture resistance designs. Typically, such films are manufactured with multi-layering systems. Each of the layers has different polymers which functionally improves strength. This feature is crucial in protecting the loads from sharp or rugged-edged materials that can easily puncture the film.
Pre-stretch capability
Some designs come with a pre-stretch capability. Such films allow a high degree of stretching before the film is finally applied to the load. Usually, this feature minimizes the film's usage as well as provides enhanced cling properties, closely wrapping the load. This design is useful for businesses that offset cost savings and load security.
Biodegradable options
There is a growing need for environmentally-friendly packaging solutions. New stretch films have been designed using eco-friendly materials. These films eliminate the need for plastic film which has serious negative impacts on the environment.
Choosing the appropriate 15 micron plastic wrap will depend on several factors. These include load types, methods of wrapping, and stretch film usage. Below are some of the factors that play a crucial role in the selection process.
Manufacturing quality
The quality of stretch film influences its performance characteristics greatly. The best-grade films are often manufactured using polymers that have excellent tensile strength and elongation properties. They will also have a higher puncture resistance capability. Additionally, films made through the co-extrusion process usually have better core adhesion, thus ensuring load security. Such films also ensure premium cling without sacrificing much static properties.
Load characteristics
The type of load being wrapped determines the film choice. For sharp-edged or heavy products, stronger films have better thickness and puncture resistance. For irregularly shaped loads, machines that are pre-stretched should be used to tightly secure the load. However, lighter loads can do with thinner films.
Film gauge
The gauge or thickness of the film is one of the most important factors when selecting pallet wrap. Thicker films, generally, provide more strength and security. Normally, these films are used in heavier industrial applications. Thinner films are lightweight. Normally, these films are used in lighter applications and can as well offer cost savings.
Manual vs. machine wrapping
Depending on whether the load is manually or mechanically wrapped, the film choice varies. For instance, machine wrapping requires more uniform and thinner films for better tension control. On the other hand, hand wrapping allows thicker films for better grip and handling.
Environmental considerations
In the modern world, there are more concerns about the environment. Films constructed from recyclable or biodegradable materials are gaining popularity. Such options could significantly lower the ecological impacts and provide greater sustainability.
15-micron stretch film is applied in numerous cases that need efficient load wrapping and securing. Below are some common scenarios highlighting this film's versatility and usefulness.
Industrial packaging
15-micron clear plastic wrap is much more commonly used in industrial environments to wrap palleted goods for storing or shipping them. Its elasticity and transparency allow easy identification of products within the film. It also protects wrapped products from dust, dirt, and moisture. Its ideal thickness is a balance between strength and stretchability.
Retail packaging
In retail businesses, couching shrink plastic wrap is popularly used to wrap non-food items like paper and plastics. Such films will keep the wrapped products neat and tidy on store shelves. They will also prevent them from being damaged or developing dust. The film gives products a shiny and attractive look to customers. It also provides a gauge of protection against theft. In some cases, it is used for grouped products to give the consumer a view of how many products are in the pack.
Transportation
During shipment, 15 micron wrap is used to secure stacked items on pallets. The film holds the items in place to avoid movement and potential damage as the items are being transported. It also minimizes the chances of different items colliding with each other, thus eliminating possible damage. The transparency nature of the film also allows shipping companies to inspect items without athwarting the load.
Food packaging
Mostly, stretch film is used to wrap perishable food products. Some of these products include fruits, vegetables, meat, and cheese in grocery stores. Unlike other plastics, stretch film is breathable. This means it allows air to pass through the film and reach food products wrapped with vented film. This feature inhibits the growth of mold and extends the products' freshness. The film also offers a gauge of protection against contaminants and keeps the products intact.
Warehouse storage
In warehouses, 15 micron clear plastic wrap is used to wrap equipment and inventory that are meant to be stored. The film provides both protective and stabilizing effects on the products, minimizing the chances of dust and moisture accumulation while also preventing items from getting mixed. The stretch film acts as an identification tool, making it easy to track different products within a warehouse.
Below are some of the frequently asked questions about 15-micron stretch film, together with their answers for further clarification.
Again, the term 'micron' refers to the unit of measurement gauging film thickness. Therefore, 15-micron stretch film refers to the plastic film that is 15 microns thick. This type of film is extensively used for packaging and has achieved popularity due to its exceptional balance between elasticity and durability.
Some of the benefits of 15-micron stretch film include enhanced load security, cost savings due to less film usage, puncture resistance, and protection from dust, dirt, moisture, and other harmful elements.
Often, 15-micron stretch films are manufactured from LLDPE. It is one of the most recyclable plastics. Unfortunately, the recycling rate of stretch films is low. This happens because they are largely contaminated with other types of plastics.
One of the most negative impacts of 15-micron stretch film on the environment is plastic pollution. Generally, plastics take several years to decompose. Nevertheless, there are biodegradable and recyclable alternatives that reduce stretch film environmental impacts. These options are eco-friendly.
It is necessary to keep the film free from sunlight and other forms of UV rays. This is because they degrade the plastic over time. For effective elongation and use, film should be kept at an ambient temperature of around 10 °C to 30 °C.
