The sealing strip is simpler and has the same function as the zipper, which is convenient for storage. Taken together, the zipper coffee bags is the most commonly used sealed coffee packaging bags

Why do coffee bags have resealable zippers?

Zippwe coffee bags, now more colloquially known as zip-lock coffee bags, were first invented in the 1950s by a Danish inventor named Borge Madsen. 

Madsen then sold the patent for the design to Max and Edgar Ausnit, who created the company Flexigrip and began manufacturing zipper coffee bags that featured a plastic zipper. That said, the brothers refined the design and manufacturing process to make the zipper coffee bags easier to use and cheaper to produce. Early designs of the zipper coffee bags required a small piece of plastic, which had to be slid from one end to the other in order to seal the zipper coffee bags. It is Max’s son, Steven, who is credited with designing the zippers commonly used today. 

He thought of making this mechanism because the manufacturing the former version of the zipper coffee bags was quite expensive. The new zipper coffee bags were manufactured in two parts: the press to seal section and the plastic coffee bags. 

The product experienced massive success and has become as ubiquitous as the problem it addresses: maintaining the freshness of food. Or, in this case, coffee. Once coffee packaging is open, the deterioration of the product will accelerate owing to exposure to moisture and oxygen. Additionally, the loss of volatile compounds in the coffee and oxidation will have a noticeable effect on the quality within a few hours of exposure. And so, born of necessity, zipper coffee bags offer consumers the convenience of preserving the freshness of the coffee without having to transfer the beans or ground coffee into another container. 

Can resealable zippers in zipper coffee bags be recycled?

The majority of resealable zippers used in zipper coffee bags are usually made from low-density polyethylene (LDPE) or polylactic acid (PLA).

The use of these materials can cause confusion among consumers, as each must be disposed of in different ways. 

For example, if the zipper coffee bags are made of a different material than that of the zipper, it may have to be separated from the packaging before recycling.

Understanding the materials and terminology regarding coffee packaging requires due diligence, and it is essential roasters convey this information to consumers.

For instance, recyclable materials can be broken down and made into something else. For these items to be recycled, they must be disposed of correctly. 

If a non-recyclable item contaminates a batch at the recycling plant, it may lead to the entire lot ending up in landfill. 

Biodegradable plastics or bioplastics, such as PLA break down naturally over time. PLA is classified as a 100% bio-sourced plastic: it is made using renewable resources such as corn and sugar cane. 

Lactic acid, obtained by fermenting sugar or starch, is then transformed into a monomer called lactide. This lactide is then polymerised to produce PLA.  

It is important to note that some PLA can only be composted in industrial facilities as it requires specific oxygen levels and temperatures of 60°C (140°F).

That said, some companies now introduce an enzyme which acts as a catalyst that hastens the bioplastic’s disintegration, making it suitable for home composting.
