Hey there! As a BOPP film supplier, I've been getting a lot of questions lately about what the requirements are for BOPP film used in label printing. So, I thought I'd put together this blog post to share some insights.
1. Clarity and Transparency
When it comes to label printing, clarity is king. Customers want labels that look sharp and professional, and that means using a BOPP film with excellent clarity and transparency. You don't want any haze or distortion that could make the label text or graphics look blurry.
For labels that need to really stand out, our Super / Crystal Clear BOPP Film Jumbo Roll is a great option. It offers ultra - high transparency, making colors and images on the label pop. This type of film is perfect for high - end products where the label is a key part of the product's appeal.
On the other hand, if you're looking for a more cost - effective solution without sacrificing too much on clarity, our Normal BOPP Film Jumbo Roll can do the job. It still provides good clarity for most label printing applications and is widely used in the market.
2. Printability
Good printability is crucial for BOPP film in label printing. The film should be able to accept different printing inks and processes well. Whether it's flexographic, gravure, or digital printing, the ink needs to adhere properly to the film surface.
The surface of the BOPP film needs to be treated to improve its surface energy. A higher surface energy allows the ink to spread evenly and bond better with the film. We make sure that our BOPP films are surface - treated to the right level so that they can work well with various printing methods. This ensures that the labels come out with vivid colors, sharp details, and long - lasting print quality.
3. Tensile Strength and Durability
Labels need to withstand a lot of handling and environmental conditions. That's why the BOPP film used for label printing should have sufficient tensile strength. Tensile strength refers to the film's ability to resist breaking when pulled. A film with high tensile strength is less likely to tear during the label - making process or when the labels are applied to products.
In addition to tensile strength, durability is also important. The film should be able to resist scratches, abrasions, and chemicals. For example, if the labels are going to be used on products that are exposed to water or cleaning agents, the BOPP film needs to be able to maintain its integrity. Our BOPP films are designed to be tough and durable, so you can be confident that the labels will look good throughout the product's lifespan.
4. Adhesion Properties
For self - adhesive labels, the BOPP film needs to have good adhesion properties with the adhesive. The adhesive should stick firmly to the film without peeling off easily. At the same time, when the label is applied to the product surface, it should adhere well and stay in place.
We test the adhesion of our BOPP films with different types of adhesives to ensure compatibility. This way, you can choose the right combination of film and adhesive for your specific label application. Whether it's for a smooth glass surface or a rough plastic container, our films can provide reliable adhesion.
5. Thickness and Uniformity
The thickness of the BOPP film is an important factor in label printing. Different label applications may require different film thicknesses. Thicker films are generally more rigid and may be suitable for labels that need to maintain their shape, while thinner films can be more flexible and conform better to curved surfaces.
Uniformity in thickness is also crucial. Any variations in thickness can lead to uneven printing results or problems during the label - applying process. We use advanced manufacturing techniques to ensure that our BOPP films have a consistent thickness across the entire roll. This helps to produce high - quality labels with uniform appearance.
6. Static Resistance
Static electricity can cause a lot of problems in label printing. It can attract dust and debris, which can affect the print quality. It can also cause the film to stick together during handling, making it difficult to process.
Our BOPP films are treated to have good static resistance. This reduces the build - up of static electricity, making the film easier to handle during the label - making process. You'll notice fewer issues with dust attraction and film sticking, which ultimately leads to a more efficient production process.
7. Environmental Considerations
In today's world, environmental friendliness is becoming more and more important. Many customers are looking for BOPP films that are recyclable or made from sustainable materials.
We're committed to environmental protection. Our BOPP films are designed to be as eco - friendly as possible. We're constantly researching and developing new ways to reduce our environmental impact, such as using more sustainable raw materials and improving the recycling process of our films.
