Clear Packaging Technology
Cutting-Edge Manufacturing Technology
In Taiwan, most food vacuum bags are still produced through a “one machine, one factory” patchwork process. After taking an order, suppliers often outsource film blowing, lamination, and bag making. This makes it difficult to track progress and even harder to guarantee quality.
We are different.
At Shin Harn, everything—from raw plastic materials to finished bags—is completed under one roof. So when customers ask about production status, we can provide the most immediate and accurate answers.
We are not a “let us ask someone else for you” company.
Shin Harn is the production site.

Clear Packaging Transactions
Don’t let middlemen hold back your packaging
Many so-called “factories” are just brokers: They mark up prices, deliver unstable quality, and blame others when things go wrong. And when materials don’t match your machines, they won’t even dare step into your plant.
We are different.
Shin Harn is true in-house manufacturing—transparent pricing and full quality control.
Most important: we actually fix your production issues.
Others only sell you bags.We’re the ones who make sure they run smoothly on your machines.
See the Real Factory!
Many “fake factories” exist in the market. Once you check the address, it’s just a house or a small office. A real factory with film-blowing, lamination, and bag-making machines needs nearly 1,000 sq ft of space.
