Seinichi is a Japan-quality manufacturer of plastic zipper storage bags. All of our activities, from production to inspection, are carried out right here in Japan, and our products are designed and developed giving priority to safety and the peace of mind of our customers. Every day we look for ways to innovate our products and make them easier to use.
One of our strengths is the implementation of a “safe & secure” production management system that allows us to guarantee quality throughout the manufacturing process—extending from production to inspection—which is carried out entirely in Japan.
The production process starts with warehousing and acceptance of source materials, followed by zipper attachment, and then bag manufacture. Each process is subject to a range of quality inspections, including standard-compliance testing, seal strength testing, zipper strength testing, zipper adhesive strength testing, pinhole testing, and appearance inspections. If a defect is found at any point, all products immediately undergo a sheet-fed inspection to completely stop defective products from being shipped.
In addition to the individual process inspections, our inspection division also performs a thorough shipment inspection based on nine criteria. Only those products that meet all nine criteria are shipped.
