On-Site Inspection and Successful Trial Production

Before delivery, the Indian customer visited our factory for a detailed inspection of the PP hollow sheet production line. Our technical team introduced the machine configuration, mechanical structure, electrical control system and operating process.

The customer carefully inspected the equipment and participated in the actual machine trial.

The target product specifications were:

* Product: PP Hollow / Corrugated Sheet

* Thickness: 3 mm

* Basis Weight: 325 GSM

* Material: PP-based formulation

After process adjustment, the extrusion line operated smoothly and continuously. The finished sheets showed uniform thickness, stable hollow structure, good surface quality and consistent forming performance.

The successful trial confirmed that the production line could meet the customer’s requirements for lightweight PP hollow sheet manufacturing.

Customized Configuration for Efficient Production

This PP hollow sheet extrusion machine was customized according to the customer’s actual production requirements and integrates several auxiliary systems to improve production efficiency and finished product quality.

Online Crushing and Recycling System

The line is equipped with an online crushing and recycling system. Edge trims and eligible production scrap can be crushed and returned to the production process according to the required formulation.

This helps manufacturers reduce material waste, improve raw material utilization and lower overall production costs, which is especially important for large-scale PP hollow sheet production.

Double-Side Corona Treatment

A double-side corona treatment unit is integrated into the production line to improve the surface energy and adhesion performance of PP sheets.

This treatment makes the finished sheets more suitable for printing, coating, laminating and other downstream applications, expanding their use in packaging, advertising and industrial protection.

PP Hollow Sheet Applications and Market Potential

PP hollow sheets, also known as PP corrugated plastic sheets, PP fluted sheets or polypropylene hollow sheets, are lightweight, moisture-resistant, reusable and recyclable.

They are widely used for:

* Packaging boxes and logistics turnover boxes

* Fruit and vegetable packaging

* Industrial product separators

* Advertising and printing boards

* Floor and wall protection

* Industrial protective packaging

* Agricultural applications

Demand for PP hollow sheets continues to develop across India, Southeast Asia, the Middle East, Africa and Latin America, driven by the packaging, logistics, advertising and construction industries.
