Bubble Mailers with Self-Adhesive Strip (HK) and Red Tear Tape. These mailers feature a self-adhesive sealing strip and an integrated red tear tape for easy opening. The tear strip allows recipients to open the mailer with a single, smooth motion. Perforations on both sides of the flap clearly indicate where to start tearing—either from the left or right—for quick and convenient access. One of the key advantages of this design is its tamper-evident construction: once the flap is torn open, it cannot be resealed, effectively preventing any unauthorized access or tampering with the contents.
We offer flexographic printing in up to 6 colors on all standard mailer sizes, from A/11 to K/20, including CD format.
In addition, we provide CMYK offset printing for sizes ranging from A/11 to E/15, as well as CD.
We are one of the very few companies worldwide capable of producing mailers with double-sided registered printing using both of these printing methods.
WHAT DO YOU NEED TO DECIDE TO PLACE AN ORDER?
1. Provide artwork files or a description of the print you’re interested in.
We select the appropriate printing technology based on the materials you send us: a description, a reference file, or a print-ready file.
2. Choose the bubble mailer sizes you need.
Most customers select more than one format to match the variety of products they ship.
3. Specify the order quantity.
A quarterly volume is the most common choice.

Technical info for specialists: Bubble mailers are assembled from two separate paper rolls — one for the back and one for the front — which means we do not register front and back prints to align perfectly.
What this means in practice:
If the print with logos/branding is on the front, then the back can be unprinted, single-color APLA, or single-color large-format seamless printing.
If the print with logos/branding is on the back, then the front can be unprinted, single-color APLA, or single-color large-format seamless printing.
Prints for quantities above 5,000 pcs are made on white offset paper 75 g/m². Offset paper is most often chosen for CMYK printing and also because it is more affordable than kraft paper.

Enhanced bubble envelope design — affordable and easy to use

To encourage and enable end users to sort their waste properly, PACKAIR offers only modern bubble envelopes designed for effortless and quick recycling.

Types of CMYK Printing to Choose From
CMYK+0 PRINT – coverage of 5% to 95% of the surface (OFFSET technology)
Multicolor CMYK printing, single-sided, with less than 100% print coverage (unprinted strip on the left and right edges)
Printing on the front (CMYK+0) or back (0+CMYK) of the envelope
Minimum CMYK print order varies depending on the format (different standard formats apply for CMYK)
CMYK+0 PRINT – 100% surface coverage (OFFSET technology)
Multicolor CMYK printing, single-sided, with full print coverage (except for unprinted strips on the left and right edges)
Printing on the front (CMYK+0) or back (0+CMYK) of the envelope
Minimum CMYK print order varies depending on the format (different standard formats apply for CMYK)
1-4 PANTONE PRINT – 5%-100% surface coverage (OFFSET technology)
Printing with up to 4 Pantone colors, single-sided, with print coverage below 100% (unprinted strip on the left and right edges)
Print on the front (4+0) or back (0+4) of the envelope
Minimum order quantity for 4 PANTONE colors varies depending on the format (standard formats same as for CMYK)
Good to know: Colours are selected based on the files provided or as specified by the Client. The print area for CMYK technology encompasses the entire external surface of the mailer.
Information for specialists: Bubble mailers are assembled from two independent paper rolls, a back roll and a front roll – consequently, we cannot ensure the alignment of the front print with the back print, and vice versa. What this means in practical terms: If a print with imprints/logos is located on the front, the back can be unprinted, or a solid single colour, or feature a large-scale, edge-to-edge print. Conversely, if a print with imprints/logos is on the back, the front can be unprinted, or a solid single colour, or feature a large-scale, edge-to-edge print.
We exclusively apply CMYK prints to bubble mailers using 75 g/m² white offset paper. Offset paper is the most frequently chosen option for CMYK printing, also favoured due to its more competitive pricing compared to kraft paper.
Regarding product packaging:
Peeling off the silicone strip covering the hotmelt HK adhesive
Closing the flap and sending the mailer
Our bubble mailers feature an enhanced design that is both cost-effective and user-friendly.
This improved construction allows for the effortless separation of the paper from the film, facilitating easy waste sorting at the recipient’s home. It’s likely none of us relish spending several minutes on the tedious (and often impossible) task of separating paper from film, which leads most people to dispose of bubble mailers in mixed waste after receiving a shipment. To enable and encourage end-users to engage in selective waste collection, PACKAIR exclusively offers contemporary bubble mailers where recycling is remarkably straightforward and quick.
