PE Double twist stationery buckle Overview
PE (Polyethylene) Double Twist Stationery Buckle is a lightweight, flexible, and economical fastening component widely used for temporary bundling, organizing, and securing lightweight items. Polyethylene is chosen for this application due to its flexibility, excellent impact resistance, and low cost, making it suitable for disposable or high-volume consumer-grade products.
Product Parameters
As “Double Twist Stationery Buckles” are not standard machine fasteners, they do not follow ISO/DIN specifications. Dimensions are proportional to the intended bundle size. The sizes below are representative of common products in the market:
| Designation | Overall Length (L) | Body Width (W) | Loop Diameter (Outer D) | Max Bundle Thickness (Approx.) |
| Small (S) | 30 mm | 5 mm | 10 mm | 5 mm |
| Medium (M) | 45 mm | 8 mm | 15 mm | 10 mm |
| Large (L) | 60 mm | 10 mm | 20 mm | 15 mm |
Key Features
The choice of PE material influences the buckle’s functional characteristics by prioritizing flexibility and resilience:
High Impact Resistance: PE is very tough and will not shatter, even if dropped or bent repeatedly.
Flexibility/Ductility: The buckle can tolerate significant bending and stretching, reducing the chance of breakage during application.
Excellent Moisture Resistance: PE is highly water-resistant, making the buckle suitable for damp or humid environments without degradation.
Low Cost: Polyethylene is one of the most economical polymers, supporting high-volume, low-cost production.
Advantages
| Category | Advantage (Pro) | Disadvantage (Con) |
| Functionality | Quick Release: Allows for very fast, tool-free locking and unlocking. Reusable and Resilient. | Low Stiffenss: Lower strength and stiffness compared to POM or PP buckles; may stretch slightly under tension. |
| Material | Extremely Economical and Highly Impact Resistant. Excellent moisture resistance. | Lower Fatigue Life: The locking mechanism may wear faster than POM after thousands of cycles. Poor UV Resistance. |
| Cost | Ideal for high-volume consumer goods and disposable packaging solutions. | Limited temperature range (melts/softens easily at elevated temperatures). |
Applications
The PE Double Twist Stationery Buckle is ideal for consumer and commercial applications demanding high-volume, low-cost, reusable binding:
Consumer Packaging: Temporarily securing lightweight bundled retail goods, fresh produce, or small items during transport.
Office and Document Management: Economical binding of stacks of documents or papers in non-critical environments.
Hobby and Crafting: Used for simple, temporary securing of light materials.
Horticulture: Used for tying and bundling lightweight plants or gardening materials due to its weather and moisture resistance.
Packaging & Delivery
Standard packaging includes PE bag, foam cover, and one double-deck corrugated outer carton for safety during transit. Delivery time is 5-15 working days depending on the quantity.
