Cellophane is also used in transparent pressure-sensitive tape, tubing, and many other similar applications. Cellophane is compostable and biodegradable, and can be obtained from biomaterials. [1] The original production process uses carbon disulfide (CS 2), which has been found to be highly toxic to workers. [2]
The global production of CA materials was over 800,000 tonnes (790,000 long tons; 880,000 short tons) per year in 2008. While it was initially believed that CA was virtually non-biodegradable, it has been shown that after initial partial deacetylation, the polymer's cellulose backbone is readily biodegraded by cellulase enzymes.
In typical parlance, the word biodegradable is distinct in meaning from compostable.While biodegradable simply means an object is capable of being decomposed by bacteria or other living organisms, "compostable" in the plastic industry is defined as able to decompose in aerobic environments that are maintained under specific controlled temperature and humidity conditions.
This tape has adhesive on both sides, and is used to stick two surfaces together. Duct tape Usually gray in color, this tape is backed with scrim, often coated with rubber or plastic. [1] Elastic therapeutic tape Also known as "K tape" and "kinesiology tape", it is an elastic-cotton strip backed with acrylic adhesive.
Biodegradable additives can convert the plastic degradation process to one of biodegradation. Instead of being degraded simply by environmental factors, such as sunlight (photo-oxidation) or heat (thermal degradation), biodegradable additives allow polymers to be degraded by microorganisms and bacteria through direct or indirect attack.
Flagging is a coloured non-adhesive tape used in marking objects. It is commonly made of PVC or vinyl , though wood fibre cellulose-based biodegradable flagging also exists. Uses
