• Adhesive Type: Acrylic adhesive provides excellent UV resistance and aging properties, making it suitable for long-term storage. Hot melt adhesive offers aggressive tack and is ideal for immediate bonding on corrugated boxes.
• Thickness: Tape thickness typically ranges from 35 to 60 microns. Thicker tapes offer higher tensile strength and durability.
• Width and Length: Standard widths are 48mm and 72mm, with roll lengths from 50 to 200 meters. Custom sizes are available for specific needs.
• Tensile Strength: BOPP tapes have tensile strengths between 40 N/cm and 60 N/cm, while PVC tapes can reach up to 80 N/cm.

Plastic Strap & Tape FAQ Common Questions Collection

Question: What is the difference between polypropylene and polyester plastic strapping?

Answer: Polypropylene (PP) strapping is a cost-effective option with good elongation, making it suitable for light to medium-duty applications where some flexibility is needed. It resists moisture and chemicals but has lower tensile strength. Polyester (PET) strapping, on the other hand, has high tensile strength and minimal stretch, ideal for heavy-duty loads that require stability and high tension. PET also performs better under extreme temperatures. Choosing between them depends on your load requirements, budget, and environmental conditions.

Question: How do I select the right plastic tape for shipping boxes?

Answer: When selecting plastic tape for shipping, consider the box weight, storage conditions, and required security. For standard corrugated boxes, BOPP tape with acrylic adhesive is recommended due to its strong adhesion and resistance to aging. If boxes are stored in varying temperatures, acrylic adhesive maintains performance. For heavier boxes or those exposed to rough handling, opt for a thicker tape (50+ microns) with high tensile strength. Additionally, tamper-evident or printed tapes can enhance security. Always test the tape on your specific box material to ensure proper adhesion.

Question: Can plastic strap and tape be used together for packaging?

Answer: Yes, combining plastic strap and tape can provide enhanced security and stability for shipments. Use plastic strapping to unitize and secure the main load, especially for palletized goods, as it offers high tensile strength to prevent shifting during transit. Then, apply plastic tape to seal box flaps, reinforce edges, or provide a tamper-evident seal. This dual approach is common in logistics to handle both heavy compression forces and detailed sealing needs. Ensure compatibility by checking that the strap does not damage the tape and that both materials can withstand the same environmental conditions.

Applications and Best Practices

Plastic strap and tape are essential in various industries. In logistics, they secure pallets and containers for transport. Manufacturing plants use them to bundle raw materials or finished products. Retailers rely on them for in-store displays and inventory management. To maximize efficiency, always match the product specifications to your load requirements. Use tensioners and sealers for straps to ensure proper application, and apply tape with dispensers for consistent pressure and adhesion. Regular inspection of equipment and material condition helps maintain performance and safety.
