Talk:Food packaging

This article should be merged with the main Packaging page

Proposed merger/organization
At present, most of this article is redundant with the content of Packaging and labelling. That has been updated and expanded and should be the primary/starting page for packaging. A sub-category of packaging should be the "food packaging" page. This would not reiterate the material on the primary packaging page. It would add discussion of specific food packaging items: Regulations (USA: FDA and USDA), Haccp, Good manufacturing practices, food safety, etc. Rlsheehan, May 27, 2007

I don't know the US law, but I think in Europe the legislation for "Food packing" is very specialised, so there should be both article (perhaps with lesser redundancy). Plehn (talk) —Preceding comment was added at 20:59, 12 April 2008 (UTC)


 * No way. That would make for overly huge or vague articles. 72.40.152.209 (talk) 08:40, 25 March 2010 (UTC)

Legal materials?
This needs a list of approved materials. I don't think you can ship a bottle of orange juice made from PVC, lead, wood, or leather. Plastics aren't allowed to have carcinogenic plasticizers. 72.40.152.209 (talk) 08:40, 25 March 2010 (UTC)

Expert help
We need editors who are experts in food packaging to expand this article. As it now sits, it is basically the same as Packaging and labeling. There are many areas of regulation, processing, quality, and package constructions that are specific to food packaging. Please help this weak article. Pkgx (talk) 17:21, 26 November 2013 (UTC)


 * Yes, the tag indicates that what this poor article needs is special topical knowledge. Thus if it scares off editors who know how to organize but not so much about the topic, no problem. I hadn't thought of the article that way, having assumed that an encyclopedia article more needs clarity than depth of detail. You, or someone similarly equipped, might be able present a list of deficiencies, to be used by the expert if one is eventually found. As for the other article overlapping this one's contents, you're quite right but perhaps it won't take an expert to establish a proper balance and connection between them.

Biodegradable food packaging
I'm wondering whether we shouldn't mention something about organically made food packaging (by which I mean packaging made mostly by plants). In Africa, the calabash is used to hold water, so its water-resistant. It could as such replace say plastic yoghurt pots (it can be filled in a factory with yoghurt, and then sealed with say bees wax or resin). This way, the whole thing can be discarded in nature (no seperation of plastic and yoghurt for recyling is needed, if say the yoghurt in the pot wasn't eaten and was disposed off. An added advantage is that the containers can be grown at the factory, so this job doesn't need to be outsourced, and then transported between the plastic factory and the yoghurt factory (it can all be done in-situ). Depending on the calabash cultivar used, several container shapes could be made. If the adding of a company logo is also needed, it can be added to the calabash peel by removing pigment in a zone on the peel. See http://hoholok.com/stamp-makes-plastic-around-organic-fruit-and-vegetables-unnecessary/

For this article, it's probably also important to mention bioplastics (that can be composted at ambient temperature) used as packaging. They too would offer the same benefits as the organic packaging method mentioned above. As such, this type of packaging + the food wuld thus still have a commercial value (as being directly useful as fertilizer). By comparison, foods with artificial packaging (that hence doesn't compost at all) would not have a positive commercial value, and rather represent a cost for companies (as it would require prior seperation of food + packaging to allow the food being used as compost, and the package be discarded or recycled).

Reviewer 2
Hi,

The article is well-organized. If the article can be shorter, it may be more convenient for readers to read and obtain information. Super good work！

Review
Hello, I have read your article and I find it very complete and well organized!

My only observation is that sometimes some sentences are a bit long, so it can be difficult to follow their logical meaning. So my suggestion is to split them in order to keep them clear.

Very good job! :) @ BenedettaFlam (talk) 14:15, 1 July 2022 (UTC)


 * Thank you, I'll try to fix the lenght-problem! Filippo Ghisoni (talk) 14:20, 1 July 2022 (UTC)

Article Review
Very well done article. The topic seems to be totally covered with exhaustive explaination. I appreciated the various images too. Well done! Fpalmese (talk) 14:45, 1 July 2022 (UTC)

Observations and suggestions for improvements
The following observations and suggestions for improvements were collected, following expert review of the article within the Science, Technology, Society and Wikipedia course at the Politecnico di Milano, in June 2022.

Typos to be corrected: - "resource loss and CO2 production" 2 had to be subscript

Other: "into one box being made usually out of corrugated cardboard." There are a lot of secondary packaging made of other materials, I don't think that "usually" is appropriate here

"like PFAS"				first-time use of the acronym, it should at least be linked to https://en.wikipedia.org/wiki/Per-_and_polyfluoroalkyl_substances

"Plastic packaging being used is usually non-biodegradable due to possible interactions with the food. Also, biodegradable polymers often require special composting conditions to properly degrade. Normal sealed landfill conditions do not promote biodegradation. Biodegradable plastics include biodegradable films and coatings synthesized from organic materials and microbial polymers. Some package materials are edible. For example, pharmaceuticals are sometimes in capsules made of gelatin, starch, potato or other materials. Newer bioplastics, films and products are being developed"			this section is a bit confusing

"to slow down the metabolic process of food product" 		had to be revised, also the non-metabolic process is slowed down.

"Trends in food packaging" section			The list is a bit confusing and a lot of concepts are already present in the previous sections, my suggestion is to edit it in a discursive paragraph.

"Food Packaging Barrier Properties" 		In this section, the author talks about permeability and the end transmission rate. These are two different properties (correlated), and the differences should be defined and explained in order to clarify the importance of OTR and WVTR

"Oxygen barrier property"				The fact that the oxygen concentration variation in time had to measure is missing.

"Although both oxygen and water vapour represent the most studied permeants in food packaging application, other gases such as carbon dioxide (CO2) and nitrogen (N2) have also great relevance in the preservation of food products. In fact, N2 and CO2 have been employed in modified atmosphere packaging (MAP) technology to establish the correct conditions inside the package's headspace to lessen food spoiling"			This should be moved to another section

"Water vapour barrier property"			The cups approach is not the only WVTR measuring method.
