Additional Information

What's so great about these Mailing Bags?

Compostable: Our black mailing bags are made from Cornstarch, with PBAT & PLA, which are 100% compostable and biodegradable materials. They can be composted in both a home environment or a commercial facility (except for the peel and seal strip, which will need to be removed).  In an ideal composting environment they can be 100% biodegraded into organic fertilizer within 90 days.  In an ordinary environment, buried in soil or a microbial environment, the process will take up to 6 months.

Peel and Seal Closure: The standard peel and seal closure applied to these bags, makes them quick and easy to secure closed.

Print: These bags are printed with eco-friendly water-based inks. The printed message shouts loud and clear about their environmental credentials so all your customers know that you are choosing to use eco-conscious products instead of plastic.

Storage: These compostable mailing bags can be stored for approximately 1 year in cartons in a cool, dry warehouse.  The recommended storage temperature range is 10-40°C.  It is advisable to avoid storing these bags in high temperatures, sunlight or a humid environment.

packaging solutions

Expert packaging suppliers for over 40 years, with an emphasis on plastic-free packaging

In the late 1970s, two friends and colleagues, Tim Allen and Stewart Middleton saw a gap in the market for a different type of packaging supplier. At the time, other businesses were selling custom made boxes and stocking packaging consumables, but Tim and Stewart wanted to offer more than that. They wanted to give their clients additional services, such as warehouse storage and the ability to have their packaging delivered as and when it was required. Packaging Supplies was established, and the rest is history.
