What I did to change the shape of plastic bottle?
The shape was supposed to distinguish it from other plastic bottles, just like the first contour glass bottle back in 1915.

Concerns
There is ongoing concern as to the use of plastics in consumer food packaging solutions, environmental impact of the disposal of these products, as well as concerns regarding consumer safety. Karin Michaels, Associate Professor at Harvard Medical School, suggests that toxins leaching from plastics might be related to disorders in humans such as endocrine disruption. Aluminum and cyanide were found as trace elements in the examined samples but they are con…
Labelling
Plastic bottles are marked at their base with the resin identification code to indicate the material used.
Product labels are attached with adhesive or are shrunk to fit. In-mould labelling is a process of building the label into the bottle during molding.
Speciality types
An accordion bottle or collapsible bottle is a plastic bottle designed to store darkroom chemicals or any other chemical that is highly susceptible to oxidation. They work by being able to squeeze down to remove excess air from the bottle to extend the life of the product. An alternate benefit is minimizing storage, transportation, or disposal space when the bottle is empty or as the content is being dispersed, for example with water bottles used by hikers. Collapsing can also keep foods f…
