Question

Design an experiment to determine a robust design for the potato chips bag, in order to reduce the number of broken chips in the bag or even avoid breaking any chips at all.

Suppose you are the designer of potato chip bags. One thing customers care about is the number of broken chips in the bag. They prefer no broken chips. As the bag designer, what are the controllable factors and noise factors you can think of that may affect the number of broken chips in the bag. Draw a parameter diagram showing the controllable factors, uncontrollable factors and the performance metric. Design an experiment to determine a robust design for the chip bag.

Answer 1

As I am the designer of Potato chips bag. One thing I should keep in mind that customers don’t want broken chips in there packets.The motivation behind why those packs are fairly mind boggling is on the grounds that they should keep contaminants and dampness outside while all the while forestalling its draining own parts. With various layers of polymer materials in chips packet . The pack itself comprises of different layers of polymers and a slight layer of aluminum foil which goes about as an oxygen boundary. Here is a fundamental once-over of how the different polymers are organized , the situated polypropylene is within the sack, on it is a layer of low-thickness polyethylene which is trailed by a second layer of arranged polypropylene that is likewise covered by an ionomer gum which is normally alluded to as Surlyn.

For good measure I'll additionally unveil why those sacks seem, by all accounts, to be "loaded up with air". Before potato chip sacks are fixed they generally get dispatched with nitrogen so as to make an air pad . so that the chips won't get harmed. We use nitrogen gas to be filled in chips packet beacuse taking into account that how nitrogen is generally an inactive gas (doesn't handily respond with different synthetic substances) it doesn't adversely influence the flavour of the potato chips.

Here are a few reasons why i used nitrogen gas to fill potato chips packet:

1. Nitrogen protects your chips from oxygen. As oxygen is the main purpose for the spoiling of nourishment items.

2. At the point when the pocket sacks are brimming with nitrogen, clients can identify punctures or tears without any problem. Punctured packs permit the air to move in and out. On the off chance that the parcel has less air than typical, it implies the bundle ought not be purchased.

3. Nitrogen makes a pad around the chips so they don't break without any problem. Nitrogen flushing is significant for delicate with the goal that they can remain unblemished. Customers need to purchase chips, not their messed up parts.

4. Nitrogen flushing isn't a costly procedure. Our extraordinarily structured machines simply suck out the oxygen and top the deadlock pocket with nitrogen – there's nothing more needed than a couple of moments.

5. So on the off chance that we need to bundle chips or some other fresh bite, ensure we utilize the procedure of nitrogen flushing. It will keep our chips safe and will definitely increase the sale .

There is a lot of science in packaging fresh and crispy potato chips. Hope this fulfil your answer, please provide a positive feed back.
