Demand for eco-friendly packing supplies is rising day by day with the increase in the amount of garbage all over the world. Governments are finding it hard to segregate the waste and to recycle them. Environmental protection agencies and even people are urging the governments to put a ban on the use of plastic packaging supplies and introduce some eco-friendly packaging alternative.
Plastics have their own advantages such as durability, water holding capacity, insulation, and so on, for which they have many applications such as electric appliances, glasses, kitchen ware, etc. Due to all these reasons they have been in existence since long. Scientists are searching for an alternative for plastic that can give the same advantages but with biodegradable properties.
You may find it relieving that the scientists have found two alternatives for plastic which is a possible reality in the near future. Polylactic acid packaging, pulp thermoforming, and portable storage containers are some of the two alternatives that are making rounds.
Polylactic acid packaging (PLA), a non-toxic alternative for plastic comes from corn and is known to have similar properties of plastic, but it is bio-degradable. It is able to withstand temperatures up to certain extent. Due to its properties people consider it useful in medical industries as sutures and as disposable diapers. They can also be used to pack hot food products and drinks. PLAs have their own limitations in terms of packaging of some products.
Pulp thermoforming materials come from different types of recyclable scrap papers. First they turn into a paste and then they transform into the different packaging materials. These materials are biodegradable and can give same advantages that a plastic can offer in terms of packaging.
