Hey there! As a supplier of Printed BOPP Packing Tape, I often get asked about the adhesive types used in our tapes. So, I thought I'd write this blog to share some insights on that topic.
First off, let's talk about what BOPP is. BOPP stands for Biaxially Oriented Polypropylene. It's a type of plastic film that's widely used in the packaging industry because it's strong, transparent, and has good printability. That's why it's the go - to material for our printed packing tapes.
Now, onto the adhesive types. There are a few main types of adhesives used in Printed BOPP Packing Tape, and each has its own unique features and applications.
Rubber - based Adhesives
Rubber - based adhesives have been around for a long time. They're made from natural or synthetic rubber polymers. One of the big advantages of rubber - based adhesives is their excellent initial tack. That means they stick to surfaces really quickly when you apply the tape. This is great for hand - applied tapes because you can get a good bond right away without having to press down too hard.
Another plus is that rubber - based adhesives work well on a variety of surfaces, including rough or uneven ones. They can conform to the surface texture and create a strong seal. However, they do have some drawbacks. Rubber - based adhesives are more sensitive to temperature changes. In hot weather, they can become soft and may leave a sticky residue on the surface when the tape is removed. In cold weather, they can lose their flexibility and become brittle, which might cause the tape to break or not stick properly.
Acrylic Adhesives
Acrylic adhesives are becoming increasingly popular in the Printed BOPP Packing Tape industry. There are two main types: solvent - based and water - based acrylic adhesives.
Solvent - based Acrylic Adhesives
Solvent - based acrylic adhesives offer high - performance bonding. They have excellent adhesion to a wide range of materials, including plastics, metals, and glass. These adhesives provide a strong, long - lasting bond that can withstand different environmental conditions. They're less affected by temperature and humidity compared to rubber - based adhesives.
Solvent - based acrylic adhesives also have good resistance to aging and UV radiation. This means that the tape won't lose its adhesive properties or change color over time when exposed to sunlight. If you're looking for a high - quality tape for long - term storage or outdoor use, a tape with solvent - based acrylic adhesive is a great choice. You can check out our Solvent - based Acrylic Packaging Tape for more details.
However, the production of solvent - based acrylic adhesives involves the use of solvents, which can be harmful to the environment and human health if not handled properly. There are also some regulations regarding the use and disposal of these solvents.
Water - based Acrylic Adhesives
Water - based acrylic adhesives are a more environmentally friendly option. They don't contain harmful solvents, so they have lower VOC (Volatile Organic Compound) emissions. This makes them a great choice for applications where environmental concerns are a priority.
These adhesives still offer good adhesion and are suitable for many general - purpose packaging applications. They're also easy to clean up if there's any spillage during the manufacturing process. But they may not have the same level of performance as solvent - based acrylic adhesives in extreme conditions. For example, they might not adhere as well to some low - surface - energy plastics.
Hot - melt Adhesives
Hot - melt adhesives are applied in a molten state and then solidify quickly to form a bond. They're known for their fast production speed because they can be applied and set rapidly on the tape. This makes them ideal for high - volume manufacturing processes.
Hot - melt adhesives have good adhesion to a variety of substrates and are relatively resistant to moisture. They also have a wide temperature range in which they can maintain their adhesive properties. However, they may not have the same level of long - term durability as acrylic adhesives. Over time, hot - melt adhesives can become brittle, especially in cold environments, which might affect the tape's performance.
When choosing the right adhesive type for your Printed BOPP Packing Tape, you need to consider several factors. First, think about the application. If it's for general household or light - duty packaging, a rubber - based or water - based acrylic adhesive might be sufficient. For heavy - duty industrial applications or long - term storage, solvent - based acrylic adhesives are often a better choice.
The surface you'll be applying the tape to is also important. If it's a smooth, clean surface, most adhesive types will work well. But if it's a rough or oily surface, you'll need an adhesive with better tack and adhesion, like rubber - based or solvent - based acrylic adhesives.
Temperature and humidity are crucial factors too. If the tape will be used in a hot and humid environment, an adhesive that's resistant to these conditions, such as a solvent - based acrylic adhesive, is necessary.
