What is BOPP Film? A Complete Guide

BOPP film (Biaxially Oriented Polypropylene film) is a type of plastic film that is utilized for packaging, labeling, etc. It is mostly known to be clear, sturdy, and affordable. In this article, we will discuss the most frequently asked questions regarding BOPP film, such as whether it can be recycled or not, is it biodegradable, and how it is made.

What is BOPP Film?

BOPP is a two-way stretched polypropylene plastic film to strengthen and rigidize it. Stretching renders it tear-proof and elastic.

BOPP film is transparent, light, and gives a shiny finish. All these attributes render it well-suited for packaging items that need to be preserved as well as showcased desirably.

Uses of BOPP Film:

• Food Packaging: Snacks, confectionery, and other food items.
• Pharmaceutical Packaging: Tablets and drugs.
• Cosmetic Packaging: Creams, lotion bottles, etc.
• Labels: Apply product labels.

Is BOPP Film Recyclable?

Yes, BOPP film is recyclable. As polypropylene, which is one of the highly recyclable plastics, it can be reused by certain recycling processes. The procedure will differ depending on the equipment available in local recycling, so verify if your area accepts recycling of BOPP.

How to recycle BOPP efficiently:

• Clean the Film: Remove any residues such as food or adhesives.
• Check Local Laws: Some localities do not accept BOPP; therefore, it is always better to check your local laws.

How Is BOPP Film Made?

The process of manufacturing of BOPP film is very easy with some steps:

• Extrusion: Polypropylene is melted and shaped in the form of a thin sheet.
• Orientation: The sheet is oriented in two directions (length and breadth), thus it becomes stronger.
• Cooling and Treatment: Subsequently, the sheet is cooled and treated to make it printable or adhesive.

The treatment produces a film that is hard, tough, and transparent.

Is BOPP Film Biodegradable?

No, BOPP film is not biodegradable. Like most plastics, BOPP is extremely slow in degrading from the environment. While it’s a wonderful product to have due to convenience and functionality as a packing material, its environmental quality remains a problem.

If you want green alternatives, there are other such materials which are more biodegradable or renewable in character. However, efforts are being made to render BOPP more eco-friendly and reduce its impact on nature.

Advantages of BOPP Film

There must be something or the other to justify the ubiquity of BOPP film. Some of its key advantages are:

• Strength: BOPP is resistant to water, punctures, and tears.
• Transparency: The film is transparent, which is indeed great to reveal the contents of the goods.
• Cost-Effective: BOPP is more affordable compared to others.
• Versatility: It is used in a number of industries like food, cosmetics, and pharmaceutical.

Disadvantages of BOPP Film

Even if BOPP is so useful, it also has some drawbacks:

• Not Biodegradable: BOPP is not biodegradable and will not degrade on its own in nature, which is an issue of sustainability.
• Limited Barrier Protection: Where maximum protection from moisture or oxygen is required in applications, BOPP may not be the ideal choice.

Conclusion

BOPP film is a rugged, clear, and cost-effective material of immense utility across many industries. It’s ideal for packaging goods like food, medicine, and cosmetics. While it is recyclable, it is not biodegradable, and its environmental impact is therefore something to consider.
