Transcript of Hefty vs. Glad

Which brand of garbage bag is stronger and which can stretch more? ( Glad or Hefty? )
Research

Info: "Plastic bags are generally made either of HDPE or LDPE, which respectively stand for Low Density Polypropylene and High Density Polypropylene. Low density of LDPE is due to the presence of side chains in the polymer's chains, phenomenon called branching. The extra branching give special properties such as a lower Young's modulus (lower strength of the material) but higher resistance to strain (tougher material). LDPE will deform more than HDPE before reaching the yield point, neck formation and subsequent breakage of the material. HDPE will support a heavier load but will break more suddenly than LDPE, going through more limited deformation."
Hypothesis
If I do a strength/durability experiment on the Hefty and Glad garbage bags, then Glad will be the more durable bag because based on my sources, Glad tends to be the better bag in the experiments that have been done in the past.
GOAL!
Due to the affects of Experiment 2, there was no clear answer to the hypothesis. Neither one was able to overcome each other, which is why the hypothesis can neither be proved or disproved, and the Conclusion is Inconclusive. It's a Draw!
Hefty vs. Glad
Thank you!

Procedure
Experiment 1:
1. Take out one Hefty and one Glad garbage bag.
2. Take out 4-6 10 pound weights.
3.Carefully place 1 weight in each bag.
4. Lift up the Glad bag and hold it up for 5 seconds to assure that it doesn't break, or wasn't about to break. Then, do the same with the Hefty bag.
5. Repeat these actions until the bags break, record the data as you go.

Test
When we tested the bags during Experiment 1, Hefty and Glad broke at 40 pounds.
The reason for Experiment 2 was that when we kept adding 1 weight at a time and lifting it each time we added another one, that caused tension in the bag. Tension could possibly cause the bag to break faster than it usually would because the bag had already been stressed out by the previous weight. So we decided to do another experiment in which we put 40 pounds in the bag at the very beginning so that we could see how the bag would fare while it was completely fresh and strong.
After repeating Experiment 2, 2 more times after the first time, the results turned out to be rather..........

Info:
Created in 1950, this invention can be attributed to Canadians Harry Wasylyk, Larry Hansen and Frank Plomp. The green garbage bag ranked 36th among the top 50 Canadian inventions.

Info: Glad is "eco-friendly" They claim to manufacture their bags with less plastic, and that they make their bags from recycled plastic. Quote:
"Glad® Tall Kitchen Bags innovation results in a reduction of 6.5 million pounds of waste annually — it’s like keeping the equivalent of 140 million trash bags out of landfills every year."

Info:
Hefty clams that their bags are strong and that "No matter how tough the clean-up, you can count on Hefty® trash bags to take whatever you throw at them. "

Info: A test was done with Glad Forceflex and Hefty using sharp objects, and Hefty was the one that held out.

Info:
Another test was done with Glad and Hefty being one two among many other garbage bags that were being tested. Glad and Hefty were among the top bags, with Glad being the very best.
Glad uses less plastic (0.95 mils at the top section of the glad bag, and the rest of the bag is .78. Other bags are just .90 mils throughout) and it held 63.15 lbs. and had minimal punctures compared to others. The Glad bag used was the Tall Kitchen Bag.

Info:
Consumer reports did tests on several trash bags, with Glad and Hefty being the top ones ( holding about 50 pounds). The Glad Forceflex was better than the Hefty CinchSak but did a bit worse than Hefty The Gripper.
Experiment 2:
1. Take out one Hefty and one Glad garbage bag.
2. Take out 4-6 10 pound weights
3. Put in however many weights there were in the Glad bag before it broke. Do the same for the Hefty bag.
4. Lift the Glad bag up and use a stopwatch to count how long it can hold the weights before breaking, do the same for Hefty.
5.Record data as you go and repeat this experiment 1-2 more times in case of abnormalities or defects.
Items Needed:
-x6 10 pound weights
- 1 Box of Hefty Ultimate
- 1 Box of Glad ForceFlex
- Phone for stopwatch
- Paper and pen to record data
