The Restriction On Minimum Thickness Of 50 Micron On Every Type Of Packaging Film Does Not Give Any Advantage. It Needs To Be Removed. On The Contrary, It Defeats The Principle Of 3rs (Reduce, Reuse And Recycle).
Plastics Waste Management Rules, PWM 2016, have banned the carry bags made from film less than 50 micron. Later many states have banned almost every type of packaging film of thickness less than 50 micron. What is the logistic behind 50 micron? Around 1990, carry bags were made with thickness about six microns. The freely dispensed carry bags created environmental problems. Many NGOs even advocated openly that all plastics are carcinogenic. The weight of carry bags was less than 2 gm. The rag pickers were not finding it attractive to pick up the carry bags lying around or present in household waste. The light carry bags, at times leaked into water ways and into oceans. The beaches were getting littered with such carry bags. Considering the low weight of thin carry bags, later on the Maharashtra Government banned the plastic bags of less than 20 micron. The ban, however, could not be implemented effectively. Perhaps the bags were made thinner than 20 microns and still distributed freely by vendors. The thought process of increasing the thickness more than 20 microns was that increasing the thickness would increase the weight of bag to about 5 gm and the rag pickers would find it attractive to pick up. However, this did not happen, and the problem of eye soar of littered carry bags became even more intense. The Government recommended that thickness be increased to 40 micron. Now the new rules recommend the thickness to be 50 micron.
Banning is not the answer
Banning all packaging films of thickness less than 50 microns is not technically sound. Just because thickness of carry bags has to be more than 50 microns, it cannot justify the ban on special purpose functional films also to be of 50 micron. The reasons are given below.

TotalEnergies and Jindal Films To introduce Certified Circular Polypropylene
TotalEnergies and Jindal Films have joined forces to produce more sustainable flexible food packaging and labels. Using advanced recycling technology from Plastic Energy, TotalEnergies will supply Jindal Films with Certified Circular Polypropylene produced from postconsumer plastic waste. This new value-chain collaboration will divert plastic waste currently destined for incineration and landfill because it is too complex to recycle through existing schemes.
Lenzing's VEOCEL™ Brand Launches Hydrophobic Lyocell Fibres With Dry Technology
In its quest to drive greater sustainability in the personal care and hygiene industry, the VEOCEL™ brand has launched a new offering: VEOCEL™ branded lyocell fibres with dry technology which are naturally smooth and gentle on skin, ensuring comfort for sensitive skin. Absorbent hygiene products are an indispensable part of many consumers’ lives and are relied upon daily. As these are essential items, it is important that they should offer maximum comfort and relief to the user. This is demonstrated by the new VEOCEL™ branded lyocell fibres which have the capacity to provide a high level of comfort, softness and dryness, when applied in these types of products.
Simulating Injection Molding for Efficiency
Producing high-quality, plastic injection-moulded parts more quickly and cost-effectively has become a critical factor for manufacturing success in today’s global market. Instead of engaging in slow, expensive prototype iterations and test cycles to satisfy manufacturing requirements, designers, mold makers, and manufacturing professionals can leverage SOLIDWORKS® Plastics mold-filling simulation software to optimise parts for manufacturability, refine tooling to improve quality and shorten cycle times to reduce manufacturing costs
Leveraging 3D Printing for optimised Injection Molds
A guideline from Formlabs on the factors to consider before using stereolithography (SLA) 3D printed molds in the injection molding process to lower costs, reduce lead times, and bring better products to market
iglidur I151 for FDA-compliant, Detectable, Wear Resistant Parts In Food Technology
igus has developed a blue, food-compatible tribo-filament for cost effective 3D printing of special parts. iglidur I151 is blue, prints easily, and has an optimal coefficient of friction and wear. The new tribo-filament is a refinement of the easy-to-machine igus iglidur I150 all-rounder filament. Because it is blue, it can be used to manufacture special parts that are optically detectable in the food industry. Food compatibility according to the FDA and to EU Regulation 10/2011 also qualifies the high-performance polymer for use in the food and cosmetics industries.
