In the packaging industry, stretch film plays an extremely important role. However, its effectiveness depends on many factors. So, how can stretch film stick tightly together to protect goods from damage and dust? The secret lies in Vietnam PIB Masterbatch For Stretch Film. This is the optimal solution that enhances cling strength, ensures packaging quality, and optimizes the production process.
What is PIB Masterbatch?
What is PIB Masterbatch?
PIB Masterbatch is a concentrated plastic pellet containing a high proportion of Polyisobutylene (PIB) – a polymer with high viscosity and strong tackiness. Instead of using PIB in liquid form, mixing PIB into a polymer carrier (commonly LLDPE) and producing it as a masterbatch makes the manufacturing process cleaner, safer, and easier.
Vietnam PIB Masterbatch For Stretch Film is produced with advanced technology, ensuring uniform dispersion of PIB, delivering superior performance for stretch films.
The Role of Cling in Stretch Film
Cling is the core factor that enables stretch film to maximize its functions. A film with good cling can:
- Protect goods: Self-adhesion helps film layers stick tightly together, forming a solid unit that prevents cargo from shifting, toppling, or breaking during storage and transportation.
- Resist dust and moisture: The sealed film layer protects products inside from environmental impacts.
- Increase packaging efficiency: Thanks to strong cling, wrapping becomes faster without the need for additional materials such as tapes or straps.
How Vietnam PIB Masterbatch For Stretch Film Improves Cling
-
Creates a mobile tacky layer on the film surface
PIB is a high-viscosity polymer capable of “migrating” from inside the film to its surface during production. When Vietnam PIB Masterbatch For Stretch Film is added into the extrusion process at high temperatures, PIB molecules become mobile and gradually move outward. This creates a thin, uniform tacky layer on the outer surface of the film. This layer increases the surface friction coefficient, helping film layers cling tightly to each other and to packaging surfaces such as cartons, wood, or metal.
-
Improves cling without affecting structure
PIB Masterbatch is usually applied in the outer layer of multi-layer stretch films. This can improve cling by up to 20–30% compared to films without additives, minimizing the risk of cargo loosening during transportation. Importantly, PIB Masterbatch does not negatively affect the mechanical properties of the film, such as elongation or tensile strength, ensuring the film retains elasticity and tear resistance.
-
Influence of production process on effectiveness
To maximize performance, controlling the production process is crucial. Key factors include:
- Cooling temperature: If the cooling roll is maintained at 20–30°C, PIB migration occurs optimally, resulting in maximum cling. Higher cooling temperatures may reduce this effect.
- Line tension: Proper tension adjustment ensures flatter film, allowing PIB to distribute evenly and avoiding uneven cling.
- Dosage level: The amount of PIB masterbatch, typically 1–3%, should be adjusted depending on film type (manual wrap or automatic machine wrap) to achieve desired cling performance.
Advantages of Vietnam PIB Masterbatch For Stretch Film
Choosing Vietnam PIB Masterbatch for stretch film brings many outstanding advantages, helping businesses enhance product quality and optimize costs.
-
Stable and reliable quality
Vietnamese manufacturers have invested in advanced production technologies, ensuring consistent quality across batches. This allows you to maintain stable film performance without sudden changes in cling or other properties.
