Product Drawing

PE Double twist stationery buckle is made of high-density polyethylene. Its threaded connection provides a more reliable and airtight seal than push-on buckles.
Key Features
- Mechanical Structure: A male and female snap fastener are screwed together via a threaded connection, typically with multiple turns of fine thread.
- Physical Properties: Excellent toughness, good impact resistance even at low temperatures, and resistant to brittle fracture.
- Sealing Performance: The tight engagement of the threads provides a dust- and moisture-proof seal.

Advantages
- Reliable connection: Threaded connections offer stronger locking force than push-on fasteners and are less susceptible to accidental loosening due to vibration or impact.
- Leak-proof: The threaded engagement effectively prevents liquid leakage and dust intrusion, making it suitable for applications requiring a high degree of sealing.
- Durability: The PE material is wear-resistant and shatter-resistant, and the threaded design allows for repeated tightening and loosening, resulting in a long lifespan.
- Low Cost: Similar to PP push-on fasteners, this design features a mature structure and low production costs.
Applications
- Stationery Applications: Sealing lunch boxes, pencil cases, and cosmetic bags.
Packaging Applications: Cosmetic bottle caps, daily chemical product bottle caps, and food packaging (such as honey and seasoning bottles). - Outdoor products: Sealing the ends of waterproof bags and storage bags (although high-end waterproof bags use PVC/V rolls, low-end and children’s products often use PE twist-locks).
Children’s toys: Sealing the ends of bath toys and sand and water toys to prevent water leakage.
