At the same time, those with lower gauge numbers are lightweight, which makes them perfect for wrapping lighter items.
Customizations
In some cases, companies might need to use different films for diverse business needs. More plastic films are coming with different colors and cut sizes to serve various purposes. For instance, opaque options are ideal for namespaces that require privacy.
Manual vs. machine
In the plastic film realm, there are two wrapping methods. Some are designed specifically for machine application, while others are for manual use. In a scenario where a business requires more turnover, films that can be used with machines will be more effective and efficient.
Load size
Business owners should assess the weight and size of the loads that they usually handle. More films are designed to accommodate specific load sizes. Therefore, getting one that matches the requirements will help ensure success and safety.
Environmental considerations
For customers who are eco-conscious, there are some options which manufacturers make using post-consumer materials. This will help reduce the environmental imprint of plastic.
Usage conditions
To find the most suitable film, business owners should consider whether the loads will be stored indoors or outdoors. When exposed to sunlight, choose a film designed with UV protection. On the other hand, if it will be exposed to moisture, ensure that the chosen film is resistant to moisture.
Stretch and retention
Gauges that are thin offer more stretch capability. This parity assures users that they will get more wraps per roll. In situations where more is required for each roll, go for options with higher stretch capability and retention.
Price
Finally, business owners will have to select a plastic film that fits their budget while at the same time meeting their needs. Although sometimes the quality might come with a price, the benefits tend to surpass them in the long run.
Usually, BOPA film is manufactured using a technique known as the blown extrusion process. During this process, polymer resins are heated until they become elastic. After that, air bubbles are introduced into the heated resin so that it can expand to the required film thickness. Once this process is complete, the film is then cooled to solidify the BOPA film.
As earlier mentioned, BOPA is a kind of film manufactured using polyamide. It has many outstanding features like puncture resistance, mechanical strength, and tear resistance. On the flip side, stretch film is mainly manufactured using linear low-density polyethylene (LLDPE). LLDPE comes with stretchability, and that's why it's widely used for pallet wrapping and securing loads during transportation.
Yes. BOPA film is recyclable. However, to enhance the film's recyclability, users should ensure they always clean the film, especially when it has residue from multiple materials. They should also avoid combining it with other types of plastics.
Unfortunately, BOPA film is not recommended for food packaging. The primary reason is that BOPA itself is not FDA-approved for direct food contact. The good news is that there are other polyethylene films that have been tested and approved for food packaging.
Yes, there is a difference. Firstly, BOPA is manufactured from polyamide film. It has outstanding barrier properties, mechanical strength, and stretchability. Conversely, Nylon film is not as robust in terms of stretchability and barrier properties as BOPA. Nonetheless, it is also widely used in various packaging applications due to its flexibility and toughness.
Unfortunately, BOPA film is not biodegradable. This is mainly because it is synthesized from petroleum-based polymers and comes with a long molecular structure. Therefore, it won't break down easily in the environment.
It's important to note that both BOPA and LLDPE films have unique benefits that suit different uses. As discussed earlier, BOPA is known for offering exceptional mechanical strength, tear and puncture resistance, and stretch capability. All these make it ideal for security or heavy loads applications. On the flip side, LLDPE is renowned for its flexibility and low cost. That's why it is widely used for pallet wrapping. A point to note is that LLDPE offers less tensile strength compared to BOPA. To crown it up, BOPA provides better film performance in demanding environments than LLDPE.
