Definition of vented stretch film
Vented stretch film is a type of stretch wrap, or stretch film, that allows air to pass through it. It is typically used in applications where pallet loads, such as perishables and food products, need to breathe. Vented stretch films are commonly made from polyethylene plastic, although other materials, such as polypropylene and vinyl, can also be used. The two main types of vented stretch films are blown stretch film and cast stretch film, both of which use a blowing agent to create microscopic holes in the plastic film. Blown stretch wrap is produced when hot air is blown onto the molten plastic material before it cools down, causing gas bubbles to form in the plastic. Cast stretch wrap is created by mixing a chemical blowing agent into the molten plastic material and then cooling it down under pressure. At the same time, reinforced stretch films offer superior puncture resistance and tear strength than regular blown wrapping materials.
In addition to ventedstretch films, several other types of stretch wraps are available on the market today. Pre stretch film are already stretched out before they are applied to pallets or containers, meaning they require less force and therefore offer more significant cost savings on labor costs compared with hand-applied systems. Hand stretch wrap or machine stretch film applied with conventional or cast stretches can also be purchased if the product being shipped does not require air circulation through its wrapping. Finally, specialized machines known as ‘stretch wrap machines’ automate the process of wrapping pallets with vented or conventional/cast stretches for improved productivity and efficiency.
Purpose of vented stretch film
Vented stretch films are specialty stretch films used for various purposes. It’s made from blown film, a process by which plastic is extruded through a die to create a bubble that is then flattened into sheeting. It’s often used in hand stretch film applications, offering excellent cling and strength while allowing air to escape during the stretching process. This helps to prevent the formation of bubbles or “fish eyes” when wrapping with hand stretch wrap – something that occurs more frequently when using non-vented films.
Vented stretch wrap plays an essential role in applications where high clarity and visibility are desired, such as with anti static stretch wrap or cast stretch films. The vented version of these specialty stretch wraps provides an enhanced level of clarity while still maintaining its cling and strength characteristics. Vented cling stretch film is usually used to protect items from dust and moisture during transit and provide additional tamper-resistant qualities due to its clinging ability.
In addition, reinforced vented stretch films are available for extra puncture protection. These specialty stretch wrap provide added strength and tear resistance on top of their already superior cling properties. This makes them ideal for use when heavier loads need more protection against accidental tears or punctures during handling or shipping.
Overall, vented stretch film is an excellent option for many applications, offering superior cling and strength combined with the bonus of allowing airflow during application – making it easier to apply than standard non-vented versions while ensuring that items are kept safe and secure during transport.
Considerations
A. Thickness:
One of the most important considerations when choosing a vented stretch film is its thickness, which will determine how well it can protect the products and resist punctures and tears. Thicker films provide more protection, but in some cases, a thinner one may be preferable to reduce costs. It’s also important to consider your particular application’s acceptable range of thickness.
B. Length:
The length of a stretch film roll also matters, as it directly affects how many wraps are needed for a given product or package size. Shorter rolls require more wraps and can increase labor time, while longer rolls reduce the required wraps and can be more cost-effective in the long run. Make sure that the roll length you choose is appropriate for your needs.
C. Stretchability:
The stretchiness of a vented stretch film is also an essential factor to consider when making your choice, as it will affect how tightly the package can be secured without the risk of tearing or breaking. Higher-stretch films allow for greater tension when wrapping packages, resulting in tighter seals and better protection for your products; however, some applications may require non-stretchable films or have limitations on maximum stretch levels due to product shape or size.
D. Venting Capabilities:
Some types of the vented stretch film come with perforations or micro-vents along their length that allow air inside the packaging to escape while providing an effective seal at the same time; this reduces damage caused by trapped air pressure during transit or storage and helps keep contents from shifting around excessively within their wrapping. It’s essential to look for films that offer good venting capabilities if this is required for your application. Otherwise, you may experience issues with trapped air pressure causing damage to your products over time.
Tips for Selecting Vented Stretch Film
1. Determine the weight of the product being wrapped
Knowing the weight of your product will help you determine if the vented stretch film is suitable for you. It’s best to use a vented stretch film when wrapping heavier items, as they are designed to provide more stability than regular stretch films.
2. Estimate the number of wraps needed
When considering which type of stretch film to use, estimating how many wraps you need for each item being wrapped is essential. Vented stretch films provide more stability, but if you only need one or two wraps with regular stretch film, that may be the better choice.
3. Compare the thickness of different films
Stretch films come in various thicknesses, so it’s essential to compare them before purchasing the vented stretch film. If your product only needs one or two layers of wrap, choosing a thicker film would be overkill and likely more expensive than necessary. However, if you require multiple layers (or have heavier items), a thicker film may be essential to ensure maximum stability during transport.
4. Consider the length of the film
Depending on the type of palletizing system and equipment used, some companies prefer longer rolls of vented stretch films for larger applications or continuous wrapping systems on high-volume products. The length should also consider how many wraps are needed for each item and pallet and how much material is available in a roll compared to an individual sheet or cut piece.
5. Measure the stretchability of the film
Since vented stretch films offer superior strength and stability compared to traditional non-vented options, it’s crucial to test the material’s ability to be stretched and held in place before settling on a specific brand or type of wrap film for your application.
6. Consider the venting capabilities of the film
Vented stretch films are designed explicitly with perforations throughout their surface that allow air flows through while protecting against dust and water penetration at all times during transportation or storage conditions – making them ideal solutions when it comes to transporting fresh produce such as fruits and vegetables as they can maintain temperature efficiently and ensure longer shelf life by keeping out harmful allergens like pollen grains, etc. Additionally, these air circulation properties also prevent mildew growth caused by condensation build-up during transport, which can lead to food spoilage and financial loss due to businesses that rely heavily on cargo shipments from overseas locations like China.
What are the advantages of vented stretch film?
1. Prevents Moisture/Condensation Build Up:
Vented stretch film is ideal for packaging items prone to condensation or moisture build-up. The tiny vents built into the film’s surface allow moisture to escape, so it does not accumulate and cause damage to the product inside. This makes it perfect for keeping food items fresh, as well as a variety of other products like electronics or furniture.
2. Increases Air Flow:
The vents in the vented stretch film also improve air circulation, allowing stored products to remain dry and free from mold or mildew formation. This makes it ideal for use in cold storage facilities or warehouses, where airflow is restricted due to limited space. Using this film, you can ensure that the items stored are kept at optimal levels of quality and freshness without compromising their condition over time.
3. 100% Recyclable:
One of the biggest advantages of using vented stretch film is its recyclability. Compared to traditional plastic wrap, vented stretch film is made from materials that can easily be recycled with minimal effort and cost. This helps companies save money on packaging costs while still protecting their products during shipping and storage with a sustainable material choice.
4. Available in Hand Film and Machine Film:
Vented stretch film is available in both hand-applied and machine-applied options, making it easy for businesses of all sizes to find a suitable packaging solution that meets their needs and budget requirements. For hand-applied applications, several types of dispensers are available that make unrolling and applying the film much more accessible than traditional methods. In contrast, machine-applied applications offer quick speeds for wrapping large volumes of items in less time, saving businesses both money and labor costs in the long run.
