Energy-saving and Speed-up Upgrade of Packaging Paper Machine in Southeast Asia – H Paper, Vietnam
From Concept to Production: A Complete Guide to Turnkey Paper Machinery Projects

H Paper in Vietnam is an important packaging paper production enterprise in Southeast Asia, mainly producing high-strength kraft paper and corrugated base paper. The original paper machine was introduced in 2006. After years of operation, problems such as equipment aging, declining efficiency, high paper break rate, and high energy consumption have become increasingly prominent, making it difficult to meet the rapidly growing market demand and increasingly stringent environmental protection requirements. Customers urgently need to upgrade the existing paper machine to increase capacity, reduce consumption, and reduce emissions.
