LLDPE Stretch Film: The Ultimate Guide
When looking for a reliable packaging solution, LLDPE stretch wrap is worth your consideration. We’ll tell you more about what makes it unique. We’ll show you why it can help businesses and packaging operators save money and improve efficiency.
LLDPE stretch wrap is often overlooked, but it’s critical in a number of areas. It’s critical in a number of areas, from grocery preservation to securing large shipments. It can come in handy. It’s closely associated with food packaging, logistics, construction, and other industries,. It demand continues to climb. It’s made of linear low-density polyethylene (PE) with superb tensile strength and puncture resistance. It is dustproof moisture-proof and UV-resistant. The stretchability is also excellent. This article will give you a detailed introduction so that you can know more about this packaging material.
What is LLDPE stretch film?
LLDPE stretch wrap is a high-elasticity plastic packaging film made from linear low-density polyethylene (PE). It is made using the blown film production process. It is durable and puncture-resistant and has excellent tackiness. The stretchability is also very strong and can be very tightly attached to the item. Securing the items and preventing them from moving around during transportation. And with high transparency, you can see the wrapped items very clearly and easily. High strength and load stability are also good and can be very good to prevent damage to the items. The weight is also very light The key is the cost is very low, cost-effective. Many industry’s packaging and transportation processes are used. It is a reliable packaging choice for enterprises to save money.
Technical properties of LLDPE in stretch film / how is it made?
LLDPE stretch wrap is a very good packaging material. To make this kind of film, first, choose a very high-quality premium LLDPE resin. Let it melt inside the extruder. Then extrude it from the mold to form a sheet-like material. Then it goes through the cooling roll to cool down. The thickness of the sheet material is determined by controlling the gap between the mold and the chill roll. The sheet is then fed to the cast rolls. It is cooled in a water bath and hardened. This results in better transparency and flatness. Finally, it is cut into rolls and shipped in packaging materials as needed. Every step of the process, from raw material selection to production, is critical. It all affects the performance of the stretch wrap.
Advantages of LLDPE stretch film
LLDPE stretch wrap has so many benefits. It’s strong and durable, with high tensile strength and tear resistance as well. It can also resist pressure when being transported. Packaged items are hard to puncture even when they hit sharp objects. Low cost and very cost-effective. With high output, it can reduce the amount of packaging materials used very well. It can save a lot of money for enterprises. It also has strong stretchability and adaptability. It can easily wrap items with irregular shapes and sizes. Packaging tight conformity and secure wrapping. It can also be well adapted to the climate. Whether it is the wind and sun, rain, or temperature changes.All firm and unchanged. Can be very reliable to protect the goods in all kinds of weather transport safety. At the same time, LLDPE stretch wrap is also transparent and glossy. Suitable for retail packaging, can be very convenient for consumers to see the product. It enhances the attractiveness of the product. Whether it’s for transportation, storage, retail, or stretch wrap, LLDPE stretch wrap is a very good choice.
Types of LLDPE stretch film
LLDPE stretch wrap is mainly divided into two kinds cast film and blown stretch film. Cast film is made with a flat die head. The resin in the molten state is extruded onto the chill roll. Then it is quickly cooled and shaped. It has a uniform thickness and high transparency. Easy to view the goods. It’s quiet and doesn’t make noise when unfolding. But puncture resistance and adhesion are slightly poorer. Blown film is passed through a round mold. The extruded resin is expanded into bubbles and then cooled. Blown film has high tensile strength, puncture resistance, and large load capacity. It can be very good for protecting goods with irregular shapes or sharp edges, but it can be noisy when unfolded and the appearance can look blurry.
Applications of LLDPE stretch film
LLDPE stretch wrap is a very common packaging material in the packaging industry. It has good stretchability and puncture resistance. It is commonly used to wrap palletized goods. It can easily wrap heavy goods. It also has high transparency, making it easy to see the product. In agriculture, it can be used to wrap hay bales, silage, and so on. Impermeable to water, also suitable for silage fermentation. It also has UV resistance properties, which can prevent the product from being damaged by the sun. In the food and beverage industry, it is suitable for packaging perishable food. It is both safe and shelf-stable. It also fits the food very tightly and seals it perfectly. In the construction industry, it can be used for bundling and protecting raw materials. There are also many applications in the electronics industry. Because LLDPE stretch wrap can be dustproof and moisture-proof, anti-static, and protective function of electronic components. LLDPE stretch wrap is very versatile and plays an important role in various industries.
How to use and handle LLDPE stretch film correctly
When handling transportation items and packaging items. It is very important to use and handle LLDPE stretch wrap correctly. It has great flexibility and is very durable and applicable. When handling, it is best to stick the film with a roller or dispenser. Do not grip the edges directly. It will lead to uneven stretching and also easy tearing. It is best to keep the stretch ratio between 185% and 246%. Don’t pull it too tight, it will make it lose its elasticity.
LLDPE stretch wrap can adapt to different temperature environments, but you still need to be careful when storing it.
The waste film should be stored separately and taken to designated recycling bins or recycling points after cleaning. Large companies can work with waste management companies for environmentally friendly disposal. Proper use and handling of LLDPE stretch wrap can better utilize its performance advantages. It is also environmentally friendly.
How to choose the right LLDPE stretch film
There are many aspects to consider when choosing the right LLDPE stretch wrap. Firstly, the thickness of the film is very important as it determines the strength and load-bearing capacity of the film. Thicker films offer better protection but are more costly, depending on the weight and fragility of the product. Secondly, stretchability affects load retention. Higher stretchability increases load retention and reduces the amount of film needed.
Puncture resistance is also important. Especially when wrapping sharp or irregularly shaped items. Make sure the film can withstand tip punctures. In terms of clarity, films with high transparency make it easier to inspect the packaged product. It is important for companies that need to be visible for inspection.
Load retention is the ability of the film to hold a load under pressure. It depends on the specific packaging that needs to be evaluated. There is also a concern for environmental factors. Options are available for films made from recycled materials or bio-based materials. The method of use also needs to be considered. Manual or machine use each has its own characteristics. Machine use has more consistent film tension and stretch. It improves load stability.
The choice is a balance between cost and performance. Be sure to meet the necessary performance criteria. Avoid long-term damage and additional costs associated with poor selection.
