That depends on the plastic; basically polymer resin, plasticizers, and filler.

The cuticle can be likened to a plastic bag because it serves as a protective barrier, sealing in moisture and preventing external elements from entering. Just as a plastic bag keeps its contents secure and safe from contamination, the cuticle shields the nail bed and underlying tissues from bacteria and injury. Additionally, both the cuticle and a plastic bag can be flexible yet durable, adapting to their contents while maintaining their structural integrity.
He used the clear plastic sheet to protect the contents while still allowing visibility, making it easy to identify the items inside. The back sheet provides structural support and rigidity, preventing the clear plastic from bending or tearing and ensuring durability. Together, they create a functional and visually appealing presentation for the contents.

Yes, you can bring a plastic bag on a plane as part of your carry-on luggage, but it must comply with the airline's regulations regarding size and contents.
A tab is a metal or plastic ring that you pull to remove the top of a container to use the contents. The opposite of pull is push (as in doors), so perhaps the antonym would be button, or trigger, which would release the contents.
I'm not sure it's for regulating the the flow. I think it may be there to prevent someone from easily replacing the contents with, say, water.
Plastic is often used in the outer layer of products like containers, bottles, packaging, and wrapping materials. It provides protection, durability, and insulation while also allowing for visibility of the contents.
Cellophane gift bags are perfect for wrapping gifts that you want people to see but yet protect the contents from the elements or from falling out of containers. People can clearly see the contents of the package and create an appealing advertisement for the consumer.
No you can't. This is because in the first level of sorting done in recycling stations is done by hand. Having to open the plastic bag and sort through all the contents looking for recyclable goods would take up too much time. If a plastic bag is found in a recycling station it, and all its contents is thrown into the rubbish. There may be recyclable objects in your plastic bag but there could also be un-recyclable food and even harmful materials like medical equipment etc.
Pencil cases are often made from plastic because it is lightweight, durable, and more affordable compared to other materials. Plastic also provides a waterproof and easy-to-clean surface, which is helpful for protecting the contents of the pencil case.
The plastic cap acts as an insulator, reducing heat loss in a flask by preventing heat from escaping through the opening. It creates a barrier between the contents inside the flask and the surrounding environment, minimizing heat transfer through conduction and convection. This helps to maintain the temperature of the contents for a longer period of time.
