Which is Better Food Package, Glass Jar of Tin Cans ?

Glass jar is still the common packaging for jam and jellies. It is also the first choice of package for starting food  entrepreneur.
The sardine on the right was packed in a glass jar. But sooner of later, its manufacturer is going to switch to metal package.

Why?

Glass package provides an excellent protection against food spoilage. The glass itself is inert, it will not react to any chemicals and very heat resistant. It also prevent the entrance of oxygen provided with a good cap. Oxygen is needed by most bacteria and other spoilage organisms.
Glass bottle can be reused a million times as long as it is in good condition. No cracks and free from indelible materials. Just wash and sterilize it thoroughly and the bottle is ready for its next duty.

But glass are prone to breakage. One drop mistake and your product is gone for good. And, cost per piece and handling costs are high.
Tin can match the inertness of the glass package provided that it has a good lacquer coating that matches its product content. Excellent in keeping oxygen-free environment and resistance against drops and other external forces. Cost per piece and handling costs are relatively low as compare to glass jar.
But, metal packages cannot be reused and it is prone to rusting.
There are other choices of packaging that you can choose like laminated foils. But acquisition cost for beginners is too high.

Is it Okey to Reuse Jar Caps?

Do you know why bottle packaging is very popular?
Glass package provides an excellent protection against food spoilage. The glass itself is inert, it will not react to any chemicals and very heat resistant. It also prevent the entrance of oxygen provided with a good cap. Oxygen is needed by most bacteria and other spoilage organisms.
Glass bottle can be reused a million times as long as it is in good condition. No cracks and free from indelible materials. Just wash and sterilize it thoroughly and the bottle is ready for its next duty.
The common mistake for most of us is we reuse the glass jar cap. Cap can be reused but it’s not recommended. A good cap is made of well painted metal with a good rubber-like laminate on the inside. Laminate’s function is to seal the jar completely or to make it airtight. When you open a glass jar, you will notice a round narrow marking caused by the glass lid. This marking makes the cap less effective in providing the whole package an airtight environment.  Plus the rubber-like laminate is not as inert as the glass jar, it might contain some damage due to capping pressure.  It might also absorb the flavor and aroma of its previous content.

Packaging is Good Enough? Potato Chips and Toasted Bread

Take a look at two photos below and read the review post about functions of food packaging.
potato-chips
toasted-bread
Functions of Food Packaging:
1. provide a barrier against dirt and other contaminants thus keeping the product clean
2. prevent losses. For example, packages should be securely closed to prevent leakage
3. food against physical and chemical damage. Harmful effects of air, light, insects, and rodents.
4. package design provides protection and convenience in handling and transport during distribution and marketing
5. help the customers to identify the food and instruct them how to use it correctly
6. should persuade the consumer to purchase the food.
The question is which of the two packaging performs better? You would probably say that potato packaging is better than of toasted bread. Potato chips’ package is a laminate of aluminum foil and several layers of plastics. The package was also inflated with inert gas to maintain product freshness, protect it from handling damage and maintain a long shelf life. It provides good barrier to oxygen, light, insect and dirt. It is easy to handle because of its inflated shape. The container is also beautiful, your child will like it better than bread. Number five rule is applicable only to foods like instant noodles, spaghetti and gelatin.
Toasted bread was packed in an ordinary polyethylene bag(PE). Literally, it is inferior as compare to laminated aluminum foil. Do you think  PE bag was good enough? Well, my answer is yes! Why?
1. Produce in low volumes. The product route is from manufacturer to delivery man to sari-sari stores and to consumers. Low production volume and short product route allows the product to be sold in period not more than two weeks. These allow the product to perform function 1 to 4. Are you confused?
2. The label is informative enough.
3. This product was meant to be sold to class C and D markets. You can buy it for six pesos and its enough for your morning snack. The other was also cheap but the content is in question.

Dangers in Plastic Bottles

Our ancestors uses coconut shells and bamboo stems as containers. They also use it to preserve some food stuffs.
With the advent of technology , glass containers was invented . Glass is really inert . It provide excellent protection for food from oxygen and microbial contamination.  It is also recyclable .
The drawback of  glass bottles is the weight and fragility which lead to wide acceptance of plastic containers as replacements. It is light weight and resistant to breakage.
Human are really created smart. We even preserved the water we drink.  We attempted to preserved  goods for our safety. But the plastic bottles we use to preserved foods might pose greater danger to our health.
We often recycle plastic of bottled water  by filling them repeatedly with tap water.  PET bottles or Plastic No. 1 is recommended safe for single use. According to study , repeated use might leach some carcinogenic compounds.
Bisphenol A ( BPA) is beleived to leach from polycarbonate bottles. The popular hard drinking plastic bottles and baby feeding bottles.  BPA is one of many man-made chemicals classified as endocrine disruptors, which alter the function of the endocrine system by mimicking the role of the body’s natural hormones. Hormones are secreted through endocrine glands and serve different functions throughout the body.


update as of June 19, 2016:
Low level BPA exposure is safe according to FDA. See “FDA Approved Number 7 Juice Bottle ?”


Manufacture of this containers requires enermous  amount of energy .  The fumes from factory adds to environmental pollution.  Although these plastics are easy to recycle. Most of us are not responsible and many of these used bottles go to landfills.
Are you a fan of plastic containers ? Think twice !
