PP Push type stationery buckle Overview
PP (Polypropylene) Push-Type Stationery Buckle is a widely used, low-cost plastic fastener designed for quick, secure, and reusable bundling of lightweight materials, typically in office, retail, and document management settings. Polypropylene is chosen for its excellent flexibility, fatigue resistance, and high-volume cost efficiency, making it ideal for this simple, resilient mechanism.
Product Parameters
Below are representative dimensions for common stationery/binding applications:
| Designation | Overall Length (L) | Strap/Buckle Width (W) | Locking Head Diameter (D) | Max Bundle Thickness (Grip) |
| Small (S) | 35 mm | 6 mm | 8 mm | 5 mm |
| Medium (M) | 50 mm | 9 mm | 12 mm | 10 mm |
| Large (L) | 70 mm | 12 mm | 15 mm | 15 mm |
Key Features
The use of PP ensures the buckle is tough, resilient, and economical:
High Flexural Fatigue Life: PP is excellent at handling repeated bending, meaning the locking mechanism (the snap or hinge) can be cycled thousands of times without failure.
Low Density: The buckles are extremely lightweight, making them ideal for packaging and shipping materials without adding weight.
Moisture and Chemical Resistance: PP is highly resistant to water, humidity, and many common office chemicals, ensuring durability over time.
Cost Efficiency: Polypropylene is one of the most economical engineering plastics, supporting high-volume, low-cost manufacturing.
Applications
The PP Push-Type Stationery Buckle is widely adopted in commercial and consumer settings requiring quick, reliable, and low-cost binding:
Office and Document Management: Securing reports, presentations, and archival documents that need to be accessed and re-bound frequently.
Retail Packaging: Bundling promotional items, securing small boxes, or fastening product samples.
Hobby and Crafting: Used as a simple, adjustable closure mechanism for bags, pouches, or light fabrication.
Logistics and Shipping: Temporarily bundling product kits or securing internal package contents.
Advantages
| Category | Advantage (Pro) | Disadvantage (Con) |
| Functionality | Extremely fast, intuitive push-to-lock action. Highly reusable and resilient. | Lower Load Capacity: Unsuitable for high-tension or heavy structural applications. |
| Material | Excellent Fatigue Resistance for long cycle life. Highly cost-effective for mass production. | Lower Stiffness: The mechanism may feel less rigid than one made of POM. |
| Environmental | Resistant to moisture and common solvents. | Poor UV Resistance: Prone to degradation and becoming brittle if exposed to prolonged sunlight. |
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.
