Choosing the right PP layer pad manufacturer involves more than comparing prices. Whether you’re packaging glass bottles, beverage cans, or pharmaceutical containers, your layer pads need to match your products, handling equipment, and shipping conditions.
A reliable manufacturer should help you select the right material, thickness, and edge treatment while maintaining consistent quality across orders.
This guide explains what to look for before choosing a supplier.
1. Look for a Manufacturer With In-House Production
When evaluating a PP layer pad manufacturer, start by asking whether the company produces its own corrugated polypropylene sheets.
Manufacturers with in-house production can control material selection, sheet extrusion, cutting, and finishing. They can also respond more efficiently when customers need custom specifications.
For example, Zibo Junhui Plastic operates 12 production lines with an annual production capacity of approximately 48,000 metric tons. The company handles sheet production, cutting, and heat sealing at its own factory.
Its team has worked with corrugated plastic manufacturing and development since 1994.
For buyers, this experience can be valuable when developing packaging solutions that require more than standard sheet sizes.
2. Check Material Quality and Specifications
Not all polypropylene layer pads perform the same way.
Material composition, thickness, and sheet weight can affect flexibility, durability, and suitability for different applications.
A qualified PP layer pad manufacturer should explain these differences instead of recommending one specification for every project.
Common PP Layer Pad Specifications
Here are several specifications manufactured by Junhui for different packaging applications.
| Thickness | Weight | PP Content | Application |
|---|---|---|---|
| 4 mm | 900 g/m² | 80% | Metal can packaging |
| 3.5 mm | 1,200 g/m² | 75% | Glass bottle packaging |
| 5 mm | 900 g/m² | 70% | Pallet layer pads |
| 3.3 mm | 1,000 g/m² | 75% | Glass bottle packaging |
Common sizes include 1200 × 1000 mm, 1000 × 1000 mm, and 1100 × 1100 mm.
Custom dimensions are also available, with a maximum sheet production width of 3000 mm.
Junhui offers virgin PP material options and can adjust material formulations to meet different budgets and applications.
