Tyvek® Desiccants Remain in Landfill Indefinitely

Added to packaging that needs to be kept moisture-free, those tiny small “Do Not Eat” packets filled with granules often arrive with packaged foods, drugs and durable goods to maintain a state of dryness. Referred to in the industry as a desiccant, these tiny packs are used to prolong, preserve and pstandard silica gel desiccant bad for the environment rotect goods as they travel along supply chains by removing residual water vapor from inside a sealed containers or packages that if untreated, could result in mold, mildew, rust and corrosion.

Once the sealed package is opened and the item is removed, desiccants are ultimately discarded into the trash. While these small moisture absorbers provide many positive benefits to shippers and consumers alike, the manufacturing processes and materials used to make desiccants are unfortunately negatively impacting our planet.

The majority of the desiccants implemented today are constructed of Tyvek®, a DuPont brand of synthetic flashspun nonwoven high-density polyethylene fibers, or simply put plastic. Tyvek® resembles paper and its properties –such as being difficult to tear or puncture but easily cut and waterproof against liquids while allowing water vapor to penetrate— makes this material ideal outer packaging for sorbent packets.

Because these packets are small in size, they’re difficult to recycle and the cumulative quantity of this plastic packaging material is adding up quickly in landfill where it remains indefinitely. With heightened green initiatives and a growing segment of eco-conscious consumers, Tyvek® desiccants are being scrutinized more than ever.  

False Illusion

The chemical structure of Tyvek® desiccants renders them resistant to many natural processes of degradation referred to as Oxo-degradable. Oxo-degradable plastic products do not decompose or biodegrade. Instead Tyvek® moisture absorber packets will slowly break down into smaller and smaller pieces and eventually into fine toxic micro-plastic particles.

Plastic pollution is one of the most pressing and critical environmental issues facing the planet. It is an environmental, wildlife, climate, human health and social justice issue that impact everything including the water we drink and many of the foods we consume.

For many years consumers didn’t give a second thought to how desiccants were made or what happens after they are disposed. Not anymore. Fast forward to today and the plastic desiccant packet you placed inside your sealed package has now become an ambassador for your company and your brand.

Studies show that a growing segment of consumers are expecting sustainable products wherever possible, including desiccants - the very first thing a consumer often sees as they open their prized package. If your packet is not landfill friendly, it could have a negative impact on your brand or company.

Eco-Conscious Consumers

While Tyvek® desiccants seem harmless, in reality they have a tremendous negative environmental impact and carbon footprint.  If you employ Tyvek® silica gel, molecular sieve or calcium chloride desiccants into your packaging to protect moisture-sensitive products against deterioration, peeling, mold, mildew, rust or corrosion, then you're unfortunately contributing to pollutionMicro-Pak® Dri Clay® Kraft Desiccants, litter, micro-plastic and today’s consumers recognize this.
