Will Plastic Food Cans Become a Clear Choice?

Posted April 07, 2017 12:00 AM by Engineering360 eNewsletter

This can consists of a multilayer plastic substrate that allows consumers to see the product inside while incorporating an easy-open metal lid and metal bottom. You'll be able to see what's inside of cans before buying them at the grocery story with this technology.

What happened to just using glass like they did back in the old days?

Costs,... of not only weight of the container, but to protect the breakage. When I had the fab shop, I was called in by a Pickle Factory, to fabricate a Stainless Cover on all their conveyors to protect the product from glass jars breaking on the conveyors above them and glass shards falling in the jars on the conveyors line below them.

i guess they were on the verge of being shut down by the inspector.

I buy foods that come in glass containers all the time so I don't really buy the breakage and weight concerns given how much of what is on the shelf is still in glass or can be put in glass.

It wasn't so long ago I was pondering on making my own glass melting furnace just to play around with melting the stuff down and remaking it into other things.

I was just saying, that project to put a cover on the conveyors was an easy $18,000.00 project for me.

No price was talked about, I just needed to get it done in 10 days.

Some contents are probably best left unseen until the last minute, like canned cat food. Unfortunately, what is seen cannot be unseen.

Look at your typical can on a supermarket shelf: apart from its top and bottom, its entire surface is covered with a serving suggestion picture and text relating the brand, the nutritional value, how to prepare it etc., etc., obscuring the entire surface. So, what are they going to do? Cut a hole in the label so you can see the considerably less-appetising contents in their native form without the fancy photography?

What about waste? Metals tend to degrade in landfills comparatively quickly, where plastics tend to stick around much longer and produce more toxic decomposition products.

All this so we can see the can's innards for ten seconds at the supermarket and decide to buy it or not? I don't think I have ever encountered canned goods where the contents were spoilt. Sounds to me like a pretty high ecological price to pay just to solve a non-problem.

You must feed your cats poorly. The fancy stuff I feed my spoiled rotten cats looks better than the canned tuna my wife buys for us to eat. Smells better too. They get the little cans with the fancy Italian dish names on them.

This is one of those stu . . . . . . ok, this was around a number of years back but really didn't take off. This violates the KISS principle. We should know by now what stuff looks like when it comes out of a can. Come on now. It's canned. There's a reason its less expensive.

Metal cans are easily recycled by well used processes. Very easy to separate ferrous metals from a trash stream. Glass is easily recycled as well but the savings may not be there depending on the volume.

Besides, the manufacturer has to put all that labeling on there anyways.

(All the things that Andrew just said if I took the time to read it first. GA. )

I ate food that looked very delicious but tasted like $#it,.. on the other hands,... I ate food that looked like slop... and then went back for seconds...

The problem I have with plastic containers is over time, what can be leached to the food from the plastic. Such as microwavable containers.

Even the cans, seems to be Teflon coated... and some even look to be sealed by glue or some type of adhesive.

That's what I was thinking, you can get BPA in your food as well as your bottled water.

They could just put everything in these and recycle them like coke bottles...

Used to love going to my Wife's grandparents farm where we would stock up on all sorts of stuff she preserved, vegetables, soups, fish stew and jams....You didn't want to leave them in the sunlight though....So I think breakage and sunlight exposure during shipping and loading would be a deal breaker...stacking height comes to mind as well...

that does bring back memories growing up. Going down to the dusty old basement and bring up some canned foods from the previous season.

Canned tomatoes, Tomato juice (that smelled when mom was canning), pickles, beets not to mention the jams and jellies.

With buying on line becoming so common that old brick and mortar stores are shutting down, and it has been mentioned recently in another post that grocery shopping on line may come to be, is this just a short lived venture, like the tremendous improvements to steam powered locomotives in the late 1940's? Seeing what is in the container makes no difference if you don't see it until it is delivered to your door.

Bad idea for the consumer. If the consumer now judges his purchase on appearance. What will the canning company do. Add dyes to improve appearance. Other chemicals to keep the fluid clear. What was just a short list of ingredients( Peaches, Juice usually pear and sugar) will have a long list of special ingredients just to preserve appearance. Special ingredients that will not be listed on the can because of trade secrets. That the FDA will need to approve.

Some things I would of liked to have seen in this short story, although it was interesting to do a little looking.

A. Tru - Vue, Sonoco Products Co, Silgan Plastics, Milicron.

B. Clarified Polypropylene / EVOH Structure.

C. Brand names, Perma - Safe, Klear Can.

D. Exhibition, 2016, Pack Expo

E. Description : Tru Vue can is a straight walled, contact clear, 3 piece can with flangless metal ends,top and bottom, heat sealed to the plastic sidewalls.

F. Test market: Ingles, Harris Teeter.

G. ( Manta ). Food processing companies in South Carolina.

H. www.mccallfarms.com

Apparently this comes about due to the bean counters saying sales of foods packaged​ in glass jars and metal cans are declining.

I saw this a while ago. Two problems I see, one is that the containers are see through and no mention of how much protection a transparent plastic container provides to light or UV degradation of the product inside (which tin cans didn't suffer from).

Secondly the standard packaging label is going to cover most if not all of the circumference of the tin. This fixes problem one but greatly reduces the benefits of a transparent container.

Container life expectancy is also unclear.

In the end however if it can be shown to be more environmentally friendly and just as inexpensive as the existing tin can while not introducing any further problems then by all means.

As long as we don't start seeing canned Menudo in clear plastic, I am OK with it. I don't even want to see any more Menudo in metal cans. I ate that once (just a whim), and immediately got violently ill.

Anything that appears to be canned guts in red grease is what it is. Your eyes are not lying to you, and you really do not want to eat that, even if you have a hangover.

Fresh Menudo, maybe that is OK, but it still looks like guts to me.

I've seen videos of people trying to eat it, its even worse to watch.

In a case like this if you are trying to eat healthier by switching from fast food to.....something like this, your better off with sticking with highly processed fast food.
