Three Seal Side Kraft Paper Air Bubble Film Mailer Machine （Kraft Paper Bubble Mailer Machine for Three-Seal Laminated Mailers）

This 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 three-sealed air bubble mailers (max 100/min), ideal for e-commerce small-package mailing requiring stronger sealing.

Description

As a multi-functional air bubble film bag machine (laminated with kraft paper, PE film, aluminum foil), it has three core units: bubble lamination unit, film folding unit, and three-seal edge sealing unit—differentiated from two-seal models by its sealed bottom + two-side sealing design.

First, the lamination unit bonds outer materials (kraft paper, aluminum foil, BOPP film, pearlized film) with inner bubble film; then, the folding unit shapes the laminated film into a mailer structure (with the bottom folded for sealing); finally, the edge-sealing unit seals the two sides and bottom simultaneously to form a tight three-seal mailer. Casted frames ensure low-noise operation, while the dual servo color tracking system avoids material deviation. It can produce three-seal versions of kraft paper bubble envelopes, aluminum foil laminated bubble envelopes, and EPE foam bubble envelopes—offering better leakproof and protective performance than two-seal mailers.

Features

Three-seal structure design: Seals two sides + bottom simultaneously, providing stronger sealing and leakproof performance than two-seal mailers—better protecting goods from moisture and external impact.
Multi-material compatibility: Works as kraft paper bubble mailer machine, aluminum foil bubble mailer machine, BOPP film bubble mailer machine, EPE foam bubble mailer machine—supports lamination with kraft paper, PE film, aluminum foil, pearlized film.
Efficient production: Max speed up to 100 three-seal mailers per minute, with casted frames for stable, low-noise 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 three-seal edge sealing into one line—simplifying production without separate steps.
Versatile three-seal mailers: Produces three-seal aluminum foil laminated, composite film, kraft paper, pearlized film bubble envelopes—adapting to scenarios requiring enhanced sealing.

Application

This three-seal air bubble film bag machine is widely used in e-commerce and small-package mailing needing strong sealing:

Fragile jewelry mailing: As kraft paper bubble mailer machine, it makes three-seal kraft paper bubble envelopes—eco-friendly outer layer + inner bubble cushioning + tight three-seal design protect delicate jewelry from scratches and moisture.
Electronic accessories shipping: Works as aluminum foil bubble mailer machine to produce three-seal aluminum foil laminated bubble envelopes—anti-static, moisture-proof, and three-seal structure ensures small electronics (earphones, chargers) stay intact.
Liquid cosmetics packaging: Uses BOPP film as outer layer (as BOPP film bubble mailer machine)—three-seal design prevents leakage of liquid cosmetics (serums, lotions) during transit.
E-commerce fragile parcels: Produces three-seal bubble envelopes for e-commerce platforms—100 mailers/min speed meets peak demands, and three-seal sealing ensures safe delivery of fragile goods (small glassware, handicrafts).
