Packaging that Performs

When products come with a quality guarantee like Better Packaging’s, we need to know they’re not just up to scratch, we need to be sure they’re among the best in the market … better even!

How We Test: 5 Metrics That Matter

There are a series of evaluations we carry out to make sure our recycled poly mailers meet our high performance standards and will be suitable for their intended application. These metrics are focused on the film's physical and mechanical properties;

When testing, elongation and tensile strength need to be measured with the film both lengthwise (Transverse Direction / TD) and widthwise (Machine Direction / MD) to ensure the bags aren’t going to split when pressure is applied unevenly or someone is a little ambitious in how much they might be able to squash in!

As you can imagine, seal and label adhesion is extremely important for poly mailers! If labels come off a package, it will never reach its destination and if the bag’s seal comes open, the contents will likely fall out and be lost. Big no-no’s for eCommerce packaging! How well courier labels and bag seals stick to a mailer is highly temperature dependant so we conduct our adhesion testing at 3°C (37.4°F).

Comparison: POLLAST!C vs. Recycled Alternatives

Better Packaging believes that when it comes to packaging, brands shouldn’t have to compromise between quality and sustainability … or style for that matter! Our sustainable recycled poly mailers have to perform as well if not better than other alternatives.

Here are the results our POLLAST!C Ocean Bound Plastic mailers recently achieved compared to another packaging company’s mailers made from 80% Post-Consumer Recycled (PCR) content.

Testing performed by Better Packaging Co. in July 2025. Both mailers tested were 63um thickness.The ‘80% PCR Mailer was sourced from a well-regarded Australian packaging company specialising in poly mailer production

📌 POLLAST!C mailers showed 56% greater tensile strength (TD) than competitor mailers in testing.

📌 POLLAST!C mailers showed 15-23% more stretch (TD) than competitor mailers in testing.

Uncompromised Sustainability

These results are truly extraordinary, especially considering that POLLAST!C mailers are not only made from 100% PCR, but also that that PCR is Ocean Bound Plastic pollution recovered from the environment in Southeast Asia which is often dirty or degraded from exposure, making it a challenging material to repurpose. The process required to turn this low grade raw material into mailing satchels that perform better than their ‘peers’ is what makes POLLAST!C so unique.

TL;DR: Better Packaging’s POLLAST!C mailers are better across all 5 key quality indicators — including tensile strength, elongation, and adhesion — while being made of 100% recycled Ocean Bound Plastic.

Frequently Asked Questions

What makes POLLAST!C mailers different from other recycled poly mailers?

They are made from 100% Ocean Bound Plastic and perform better in elongation and tensile strength tests than other mailers made from 80% PCR material.

Do labels stick well to POLLAST!C mailers?

Yes, extremely well. Adhesion testing carried out at low temperatures (3°C (37.4°F)) shows labels and seals sticking to POLLAST!C film quicker than other mailers made from 80% PCR material.

Do POLLASTIC mailers come with a quality guarantee?

Better Packaging Co. guarantees the performance of its products including POLLAST!C mailers, but customers are expected to familiarize themselves with any limitations described on relevant product pages on the website and purchase accordingly.
