Hi-Sheet™ (Low-ratio foamed polyethylene sheet (cap liners and seals))
The market leader in Japan
A sheet called a "cap liner (packing material)" is attached to the inside of the cap of bottles and containers for beverages and cosmetics to prevent leakage and to maintain quality.
We've been making sheets for cap liners (packing materials) since 1972.
Our Hi-Sheet™ low-ratio expanded PE sheet has the largest share in the Japanese market.
Hi-Sheet™ has clean appearance, is hygienic, and has excellent sealing performance due to its moderate cushioning properties.
Applications
● Hi-Sheet™ is suitable for cap liners (packing materials) for cosmetics, food, beverages, toiletry supply, etc.
● We have wide variety of laminated sheets with various films which you can choose from depending on your application.
