 * Packaging and the Environment **



=Introduction= On this web page you will find a presentation showing information about packaging and how it affects the environment. Included in this is a time line with the developments in packaging, voice recordings and transcripts of interviews about packaging 30 - 50 years ago and how they have changed. There is also a write up of how packaging is changing and how it will affect the enviroment in the future. We hope you enjoy our findings.

Interviews
media type="file" key="21032010.mp4" width="300" height="300" “Shopping was a pleasant experience to be done at a leisurely pace. There were plenty of knowledgeable assistants to advise and help, and people who really knew the products they were selling.” “In some ways yes and in some ways no. Today there is such a variety of shops to choose from. You really need to shop around to get the best price, especially when you’re buying larger items where as in years gone by it was easier because there wasn’t, this huge variety, to choose from. I don’t particularly like shopping centres, I prefer Glenelg. Shopping hours have changed not for the better in my opinion; some people seem to think if the shops are open they have to shop. I know it benefits people who work, but it does cut into leisure time and family time in some cases.” “Plastic is the biggest difference. Things like biscuits, flour, rice, sugar, and dried fruit could be bought loose and put into a paper bag. Now everything is packed and for food, this is better and more hygienic except companies seem to keep decreasing the quantities in packets and charging same or more.” “There are a number of food items such as meat, frozen vegetables and bread, that if you didn’t have suitable packaging and a freezer (you would not go without it). But it would mean many more trips to the supermarket. The alternative to modern packaging of meals to cook the food yourself instead of buying all these prepackaged products.”
 * Interview on packaging and the environment!**
 * 1. ** **Shopping 30-50 years ago, what was it like?**
 * 2. Do you prefer the shops today? ** **If not why?**
 * 3. ** **The differences in packaging that you have seen over the last 30-50 years – related to food**
 * 4. ** **Is there anything you couldn’t have today, if we didn’t have modern packaging techniques?**

**Task 3 Packaging**

**Task 4** Chemistry
//- strawberries// || Polymer of ethylene || Yes || Plastics, (polyethylene?) || Holds amount needed || Space wasted (small amount) || – sticky date puddings// || Wood pulp, aluminium || Yes for cardboard, and no for aluminium || Cardboard box, and aluminium foil/ cup || Good for transport || Food scraps left on packaging, not all recyclable || Future Trends of Food Packaging ** These days consumers are generally looking for either something that is cheaper, or better for the environment. This means that a lot of companies are going to be looking for simple, recyclable packaging products, like recyclable plastics, paper and cardboard. Hopefully this also means that companies will start packaging without as much wasted material.
 * **Type of food** || **Chemistry** || **Recyclable** || **Material packaged with** || **Advantages of material** || **Disadvantages of material** ||

Then again, it is the future, so we could probably say something a bit crazy. For example, maybe everyone will walk through the supermarket with green bags and soup ladles, scooping up the food they want from the shelves and weighing everything at the end. Maybe everything will be put into green bags coated in hydrophobic paint, so that liquids can be easily transported.

These future trends of packaging should benefit the environment. If packaging doesn’t change at all from now, it is going to be very bad for the environment and there will be huge landfill. So let’s hope that people also dispose of their rubbish thoughtfully, as that makes a big difference as well.

Task 5
** Report: ** // Pringles: Salt and Vinegar //  **1.Package advantages and disadvantages:** Once the package was dropped from a distanced height, it was still all in one piece. Unfortunately the chips were crushed once we had opened the container. There was no air wasted which was good, so it was unfortunate when the chips died. The Pringles container is able to hold the chips fine, but only 2 chips came out un-destroyed. The purpose of this container is to keep the chips together, without destroying them. I think most of the chips that did destroy is because the packet had a small amount of space between the chips and the sides of inside container. It is hard to tell, but most material was used, but about 10% was wasted by destroying the chips.
 * 2. Properties:**
 * 3. Materials that were wasted:**

//Thins: Original// There was enough air to protect most chips so they didn’t crash and break. The bad bit is that there was too much air and the company only gave you ¼ to ½ a packet. Plastic, with air inside, which prevents good, unbroken chips (sometimes). And not so good for storage, if it was in a container instead of a plastic bag it would be better for storage wise. The air gave the majority of the materials that were wasted. Most of the packaging was full of air which gave less for the food to be packed in.
