corn starch bag

A company that should package their products have choices through which material they use pertaining to packaging. Traditionally companies would use polystyrene materials, which are commonly injection molded or extruded pertaining to packaging. However, companies are becoming aware of the geographical impact of polystyrene, including inability of the fabric to biodegrade.

Polystyrene packaging is unable to be recycled and will have to be disposed of inside a landfill. Therefore companies are searching to use recyclable as well as biodegradable packaging materials exactly where possible. With starch-based presentation materials, the product is biodegradable but isn't an inferior material in comparison to synthetic polymer materials.

Corn Starch Structured Materials

 Instead of using packaging materials produced from synthetic polymers, new material continues to be developed using polylactic acidity (PLA), which is constructed from fermented sugars, usually out of cornstarch. The materials created from PLA are biodegradable that's important for the surroundings.

If disposed of properly, packaging material made from cornstarch will break down into carbon dioxide and water within many months. However, if the material is just not disposed of correctly cornstarch-based material will administer longer to decompose, especially if you experience no oxygen or easy available.

The corn-based packaging material is preferable for companies since the raw material, corn can be sustainable, cheap, and easy to make. Corn is the cheapest and most abundant way to obtain commercially available sugar. Synthetic polymer materials are constructed from petroleum, a non-sustainable item that can be expensive depending on the price of oil.

Corn starched packaging really does have some interesting positive aspects over synthetic materials like reduced static electricity.

Homes of PLA Materials

 Materials made from PLA have advantages and disadvantages over synthetic polymer products. Some properties of PLA are shown below:

Food Safe

 Resistant to food fats/oils

 Good for print applications

 Lower flammability

 High aroma hurdle

 UV resistant


 Recycled by way of regrinding

 PLA Grading

 The PLA material can be made into a linens or a film. Poker coaching site of PLA grades that exist for commercial customers which may be used for a variety of applications.

2002D - Thermoforming

 3051D : Injection molding

 4032D -- Film

 4042D - Thermoforming in addition to Film

 4060D - Roll film

 6201D - Staple Sheets

 7000D – Bottles

 Issues with PLA Recycling

 As PLA materials have to composted rather than recycled, for instance paper and cardboard, companies should separate the PLA materials plus the regular recyclable materials. At present, there are only just more than a hundred composting facilities the united states.

Issues With Composting

 Although PLA materials could be composted, the correct disorders must exist. If the material is deposited inside a landfill without the suitable oxygen and light, the PLA material may not decompose for decades.

Issues with PLA Usage

 PLA materials can be used for many applications but this will not compare to the uses with the more common plastic polyethylene terephthalate (PET), which is used to make bottles consumers use everyday.


 The packaging is essential to protecting materials and companies will utilize best material for the job. The advent of cornstarch-based supplies has allowed companies to decide on a packaging material that will work for the environment and still worthy of their packaging need.

The issues with PLA are well documented even so the availability of PLA packaging materials is step one in reducing packaging waste material and helping the ecosystem.

As supply chains become increasingly cognizant of the importance of going toward sustainability, greener options like corn starch packaging are now being recognized as more than a little public relations alternative.

By causing a shift toward sustainability, supply chains ultimately lower their costs because raw materials needed in making corn starch packaging is usually cheap and easy to produce. The increased usage of corn starch packaging will certainly bring its costs down further - and therefore will allow this greener option to turn into even more readily on the market.
