Why Not a Total Ban on Plastics and Not Just Carry Bags?

Municipalities and corporations have enforced laws to ban plastic carry bags and shops have been directed not to provide such bags to customers to carry the purchased goods. Instead of plastic, jute, cloth or other biodegradable quality bags are to be used.

Now this puts lot of pressure on shops and establishments to conform but this will not reduce plastic consumption unless companies are also directed not to use plastic for packing their edible or non-edible or even consumer durables.

Biscuits, soaps, edible oils, tea, coffee powder, milk, candles, fried foods, consumer durables, even car seats are covered in plastic when it is delivered to the customer,

When companies use plastic to package their goods, it reaches more homes than when a shop keeper provides plastic bags to carry the bought goods. There has been no effort to curb the use of plastics by companies.

Or is it because they have huge backlog of designed plastic wrappers and boxes that would go waste if plastic ban is implemented or is it that extra costs will be incurred in shifting to a biodegradable quality packing?

I think policy makers, consumer activists and regulatory officials should think of a total ban on plastics and not just carry bags.
