Sustainable Packaging and the Emerging Policy

Packaging Consumption is the highest (44%) and laws relating to packaging have packaging have to be dealt with utmost care.



SOME PLASTICS USED IN PACKAGINGSOME PLASTICS USED IN PACKAGING



•Waste oil application is ideal.









PVC

• Hard PVC like pipes and window profiles can be reprocessed for same applications. • Soft PVC is difficult to dispose.



• Waste is ideal for Road Applications



• Ideal to be reprocessed for fiber, if the waste is clean• Can be used for roads adding value

Corrupt Practices leads to Corruption

Reduce Corrupt PracticesReduce Corrupt Practices

-Healthy practices prevail – good for all (Govt, Industry , Public)



Government / People --- laws are made for public at l d h h i h i d l large and not those who service the industry alone. Hence government laws have to be made to eradicate bad practices, improve quality of life and products, p p q y phandle disposal and environment related problems.



Intelligence and responsibility of the g p yindustry is very high as ultimately they have to maintain the good practices, to g pavoid problems at large for the common man who consumes these products pwithout knowing the technicalities of the design in packing.g p g



Packaging Designers have to work freely with an open mind◦ Thickness of packaging

◦ Printing of promotional information including manufacturer details (mandatory)

How can they work freely in designing a package which is very important in protecting

d ti ?and preservation?

CHIPS (FOOD PRODUCT)





Permeability of moisture & oxygen from atmosphere is Permeability of moisture & oxygen from atmosphere is reduced due to higher nitrogen pressure.Nitrogen pressure reduces the overall thickness of g ppackaging layerMetalizing also reduces permeability, better lookThe bags have to be stacked with Nitrogen gas. Have seen some stores putting hole on such packs to increase stacking quantity, not realizing that nitrogen gas g q y, g g ghas to be retained till the end consumption time.Such packs cost a lot, a privilege of only branded

dproductsShelf life of packs is increased

Difficult to reprocess or convert it to pwaste oil.Bio degradability is the only answer for o eg a ab ty s t e o y a swe o disposal of such packaging.



Chips PackagesChips PackagesChips PackagesChips PackagesAam Admi’s Snacks (very fast moving)



This is an unhealthy pack for a fried food application. But heavy demand as it goes to the poorer class of y g ppeople.Shelf life is low, but supply chain methods compensate f itfor it.◦ Chips – produced locally, packed in bulk, sold to local distributor

◦ Storage : 1 or 2 daysg y

◦ Small & tiny shops buy these and put it in their own Polyethylene Packs (sold within 2 days)

◦ Buyer buys & throws the pack on the road causing concern to Buyer buys & throws the pack on the road causing concern to the environment



Advantages:Advantages:Immense business & job opportunities for lower sectors

Marketing to lower class, market potential is high

Packaging to deal with low shelf life needed for supply chainPackaging to deal with low shelf life needed for supply chain

Problems :Problems :Disposal difficult

No brandings / identity of manufacturer

Food problems if any, difficult to trackp y

Very low microns of PE bags used - against law (less than 20 or 40 microns)

Sold as tubes and not as packing difficult for law makers to identify



Sold as tubes and not as packing, difficult for law makers to identify.

Gutkha : Controversial packaging

Metalised Polymer PackagingPaper Laminate as

Substitute Packaging (Because Polymer Packaging Banned)

This trade deals with 10,000 crores of money from parallel economy providing livelihood for many in the trade at the cost of making people addicts. Also leads to memory loss, cancer,

d i iunproductivity etc.A point to carry here is banning packaging is only an excuse, whereas government will look to eradicate this product itselfP l k i ti i hi h M ti di d Polymer packaging consumption is very high. Many tiny, medium and large scale sectors were depending on this market for long.Same people in this chain can work for products like juices, healthy drinks in pouch packaging (upcoming market)drinks in pouch packaging (upcoming market).

Suggest - identify packaging composition for essential products with increased shelf life. pInform us if the package design does not conform to permitted micron size. ( k @ il )([email protected])

Government’s Concern in PackagingGovernment’s Concern in PackagingGovernment s Concern in PackagingGovernment s Concern in PackagingPackaging of Food & Pharma Products – approval of the packaging material and practices followed and leading standards adopted in developed countries.

The micron size of carry bags and general polymer packaged goods to confirm minimum The micron size of carry bags and general polymer packaged goods to confirm minimum thickness and shelf life of packaged goods.

High energy cost involved in waste reprocessing, not in line with our energy policy and energy constraint.

Di l f k i t A i f C ti d E i t Disposal of packaging waste – A serious concern for Corporations and Environment Departments. It costs enormous efforts, committed people and money to maintain the city clean.

India being a true democracy by virtue of experiences in the past and hence strict laws do not get passed by the people Habits of people for proper segregation of waste and disposal of get passed by the people. Habits of people for proper segregation of waste and disposal of house waste is still a concern and education is a problem with a democracy. States like Singapore, US, Europe literally enforce city clean policies by charging huge fines on people to make them understand what cleanliness means. It is difficult to pursue such strict polices with the democracy and political systems that exists in India. Hence people should come forward to

f change themselves for better surrounding and environment.

Currently 40 micron size is the lowest thickness to be used as per current laws. Government is not keen to change this. However, selective representation in multilayer packaging for protection and preservation have to be studied in detail by the panel of experts for healthy laws relating to packaging Government has already formed a committee of experts for compostable relating to packaging. Government has already formed a committee of experts for compostable plastic and bio polymers.
