Three-Step Automated Kraft Bag Production Line: Cold Glue → Rotary Scrape Release Liner → Easy-Tear Strip

Kraft food bags and gift kraft packaging demand reliable bonding and neat easy-open design. Many factories split gluing, release liner and tear tape into separate manual stations, causing positioning deviation, low throughput and unstable finished quality. This integrated inline equipment executes all three processes in fixed sequence to fix these manufacturing pain points.

The production order stays consistent: precision cold glue dispensing bonds kraft paper seams first. Water-based cold glue features eco safety and flexible adhesion, will not damage kraft printing layers. Afterwards, rotary scrape structure presses release liner tightly onto paper surface with no wrinkles or bubbles.

The final procedure pastes red easy-tear strips via photoelectric positioning. The whole line runs steadily at 45 m/min, yielding 3000 kraft bags hourly.All size parameters can be saved on the touch control panel for quick switching of different bag styles. The device is compatible with most existing folder gluers, matching thick kraft, food-grade kraft paper. Continuous automatic processing cuts labor input and reject rates, perfectly applicable to takeout bags, retail gift bags and logistics kraft packaging.
