Bubble mailer production process.

Both bubble mailers and poly mailers use the same blow membrane method, in which tubular film blanks are made from molten polymer. PNG’s two computer-controlled, 8-color, overprinting printing machines can quickly and accurately read printing patterns. PNG’s machines can create up to 300,000 bubble bags per day, decreasing delivery time dramatically. The printers at whglobackpack have years of experience in the bubble mailers manufacturer industry, are well trained, and can handle even the most intricate printing designs.

Step 1: Blowing the membrane

When making a blow membrane, plastic particles are melted at high temperatures before being blown into a film. Both bubble mailers and poly mailers use the same blow membrane method, in which tubular film blanks made from molten polymer are shaped into a film by being cooled and then shaped using high-pressure air. The color of the membrane may be altered. The membrane will be transparent and the color of the raw material if neither a filler nor a color master batch is employed. Numerous color master batches may be included, depending on the request of the buyer.

Step 2: Making a Printout

Bubble mailer and poly mailer both undergo the same printing procedure. The bubble mailer’s printing pattern or text is tailored to the customer’s needs. Single-color printing, two-color printing, and full-color printing are the three main categories. Customers who want a unique design printed in several colors have a much higher demand for printers and printing equipment. In addition to skilled printers, this task also requires very precise printing equipment. Overprint and ghosting will occur if the paper isn’t evenly fed through the printer.

Using automated scanners, PNG’s two computer-controlled, 8-color, overprinting printing machines can quickly and accurately read printing patterns. Clients may have their multi-color printing needs met once the scanned printing patterns are not overprinted and the equipment corrects the discrepancy automatically. Our printing equipment is the most sophisticated in the industry, with great overprinting accuracy and the capacity to create 300-resolution patterns, and the printed final pattern is clear and does not stray from the design. In addition, our printers have years of experience in the industry, are well trained, and can handle even the most intricate printing designs with ease.

Step 3: Composite

This is a unique connection between bubble mailers and poly mailers, although it is the most critical manufacturing link. The printed membrane and bubbles are composited using a casting machine.

Step 4: Cutting and assembling the bags

To complete the bubble mailer assembly process, the composite bubble film is cut to the desired size on the bag cutting machine, and the release paper is glued to the top of the seal. To prevent the items from sticking together due to the glue, they should be securely connected, the glue should be equally placed, the left and right sides should be centered, and no glue should be added to the corners.

Our firm has four completely – automated bag cutting machines that can create up to 300,000 bubble bags per day, decreasing delivery time dramatically. Turn over a big order to PNG, and you won’t have to worry about it getting there on time.

Step 5: Packaging:

The outer box is a five-layer corrugated box particularly designed for export, and it cannot be compressed to meet shipping standards without damaging the contents within.
