Two Seal Side Kraft Paper Air Bubble Film Mailer Machine - （Kraft Paper Bubble Mailer Machine for Laminated Materials）

This two-seal side machine is a kraft paper bubble mailer machine, also compatible as aluminum foil bubble mailer machine, BOPP film bubble mailer machine, EPE foam bubble mailer machine. It laminates materials (kraft paper, PE film, aluminum foil, pearlized film) to make air bubble mailers (max 120/min), ideal for e-commerce small-package mailing.

Description

As a multi-functional air bubble film bag machine (laminated with kraft paper, PE film, aluminum foil), it consists of three core units: bubble lamination unit, film folding unit, and edge sealing unit. First, the lamination unit bonds outer materials (kraft paper, aluminum foil, BOPP film, or pearlized film) with inner bubble film; then, the folding unit shapes the laminated film into a mailer structure; finally, the edge-sealing unit performs two-side sealing to form a tight two-seal mailer.

Casted frames ensure high-speed operation (max 120 mailers/min) with low noise. The advanced dual servo color tracking system enhances safety and reliability, avoiding material deviation. It can produce various bubble envelopes: kraft paper bubble envelopes (via kraft paper lamination), aluminum foil laminated bubble envelopes (as aluminum foil bubble mailer machine), and EPE foam bubble envelopes (when used as EPE foam bubble mailer machine)—meeting diverse texture and protection needs.

Feature

Multi-material compatibility: Works as kraft paper bubble mailer machine, aluminum foil bubble mailer machine, BOPP film bubble mailer machine, and EPE foam bubble mailer machine—supports lamination with kraft paper, PE film, aluminum foil, pearlized film.
High-efficiency production: Max speed up to 120 mailers per minute, with casted frames for low-noise, high-stability operation—meeting mass e-commerce mailing needs.
Advanced servo control: Dual servo color tracking system ensures precise material alignment, avoiding offset and ensuring consistent mailer size/quality.
Integrated workflow: Combines bubble lamination, film folding, and two-side sealing into one line—no separate steps, simplifying production.
Strong two-side sealing: Tight edge seals prevent moisture/dust intrusion, and the laminated bubble layer enhances impact resistance (protects against pressure, falling, collision).
Versatile mailer types: Produces aluminum foil laminated, composite film, co-extrusion, kraft paper, and pearlized film bubble envelopes—adapting to different packaging scenarios.

Application

This air bubble film bag machine (laminated with kraft paper, PE film, aluminum foil) is widely used in e-commerce and small-package mailing:

Jewelry packaging: As kraft paper bubble mailer machine, it makes kraft paper bubble envelopes—eco-friendly outer layer + inner bubble cushioning protect delicate jewelry from scratches.
Electronics mailing: Works as aluminum foil bubble mailer machine to produce aluminum foil laminated bubble envelopes—anti-static and moisture-proof, ideal for shipping small electronics (earphones, chargers).
Cosmetics packaging: Uses BOPP film or pearlized film as outer layer (as BOPP film bubble mailer machine)—transparent/pearlescent appearance showcases cosmetics while the bubble layer prevents product damage.
E-commerce small parcels: Produces various bubble envelopes for e-commerce platforms—fast 120 mailers/min speed meets peak shipping demands (e.g., shopping festivals), and the two-seal design ensures parcel safety.
