The Bio-based Film (PLA) Cycle
PLA (Poly-Lactic-Acid) is obtained Principally from corn, although it is possilbe to use other starch/sugar sources.
These plants grow by photo-synthesis, absorbing CO2 from the air, minerals and water from the soil and the energy from the sun;
The starch and sugar content of the plants is converted into lactic acid by micro-organisms by fermentation;
Lactic acid is polymerized and becomes poly-lactic acid (PLA);
PLA is extruded into film and becomes flexible Bio-based film packaging;
Once used Biofilm is composted into CO2, water and biomass;
Compost, CO2 and water are then used by plants, and so the cycle continues.
Features of PLA Film
1.100% biodegradable and Eco-friendly
The main character of PLA is 100 biodegradable which will be decomposed into carbon dioxide and water under certain temperatures and humidity. The decomposed substance is sompostable which facilitates plant growth.
2. Excellent physical properties.
The melting point of PLA is the highest among all kinds of a biodegradable polymer. It possesses high crystallinity, and transparency and can be processed through injection and thermoforming.
3. The sufficient source of raw materials
Conventional plastics are made from petroleum, whereas PLA is derived from renewable material such as corn, and thus preserves global resources, such as petroleum, wood, etc. It's strategically significant to modern China which rapidly demands resources, especially petroleum.
4.Low energy consumption
During the production process of PLA, the energy consumption is as low as 20-50% of petroleum-based plastics(PE, PP, etc.)

Technical Data Sheet of PLA Film
Poly(lactic acid) or polylactide (PLA) is a biodegradable thermoplastic derived from renewable resources such as corn starch, tapioca or sugar cane. The fermentation of starch (dextrose) yields two optically active enantiomers, namely D (-) and L (+) lactic acid. Polymerization is carried out by either direct condensation of the lactic acid monomers or by ring-opening polymerization of the cyclic diesters (lactides). The resulting resins can be easily converted into films and sheets via standard forming methods including injection and blow molding.
The properties of PLA like melting point, mechanical strength, and crystallinity depend on the proportions of the D(+) and L(-) stereoisomers in the polymer and on the molecular weight. As for other plastics, the properties of PLA films will also depend on compounding and on the manufacturing process.
Typical commercial grades are amorphous or semi-crystalline and have very good clarity and gloss and little to no odor. Films made of PLA have very high moisture vapor transmission, and very low oxygen and CO2 transmission rates. PLA films also have good chemical resistance to hydrocarbons, vegetable oils, and the like but are not resistant to polar solvents such as acetone, acetic acid and ethyl acetate.
The mechanical properties of PLA films are greatly affected by its composition and the processing conditions, that is, whether or not it is annealed or oriented and what its degree of crystallinity is. It can be formulated and processed to be flexible or rigid, and can be copolymerized with other monomers to further modify its properties.The tensile strength and elastic modulus can be similar to those of PET.1 However, typical PLA grades have a lower maximum continuous service temperature. Often plasticizers are added which (greatly) improve its flexibility, tear resistance and impact strength (pure PLA is rather brittle). Some novel grades also have much improved heat stability and can withstand temperatures up to 120°C (HDT, 0.45MPa).2 However, typical grades have a relative low heat deflection temperature in the range of 50 - 60°C. The heat performance of general purpose PLA is typically between LDPE and HDPE and its impact strength is comparable to HIPS and PP whereas impact modified grades have much higher impact strength comparable to ABS.
Most commercial PLA films are 100 percent biodegradable and compostable. However, the biodegradation time can vary greatly depending on composition, crystallinity and environmental conditions.

Frequently Asked Questions About PLA Film
PLA film is a biodegradable and environmentally-friendly film made from corn-based Polylactic Acid resin. The film has an excellent transmission rate for moisture, a high natural level of surface tension and a good transparency for UV light.
PLA, a bioplastic created from renewable and plant-based sources, can be processed in a number of ways–by extrusion such as 3D printing, injection molding, film and sheet casting, blow molding, and spinning, providing access to a wide range of product formats. As a raw material, PLA is most often made available as films or in pellets.
In the form of a film, PLA shrinks upon heating, allowing it to be used in shrink tunnels. This makes it suitable for a range of packaging applications, where it can replace oil-based plastics like polypropylene or polyester
Films made of PLA have very high moisture vapor transmission, and very low oxygen and CO2 transmission rates. They also have good chemical resistance to hydrocarbons, vegetable oils, and more. Most commercial PLA films are a 100 percent biodegradable and compostable. Their biodegradation time can vary greatly, however, depending on composition, crystallinity and environmental conditions. In addition to packaging films and wraps, applications for PLA film include disposable bags and trash liners, as well as compostable agriculture films. An example of this is compostable Mulch film.
PLA is a type of polyester made from fermented plant starch from corn, cassava, maize, sugarcane or sugar beet pulp. The sugar in these renewable materials are fermented and turned into lactic acid, when is then made into polylactic acid, or PLA.
What makes PLA special is the possibility to recover it in a composting plant. This means a reduction in the consumption of fossil fuels and petroleum derivatives, and therefore a lower environmental impact.
This feature makes it possible to close the circle, returning the composted PLA to the manufacturer in the form of compost to be used again as fertiliser in their corn plantations.
100 bushels of corn are equal to 1 metric ton of PLA.
No. PLA film will not degrade on shelves and has a similar shelf-life to other petroleum based plastics.
1. Polystine has the basic characteristics of biodegradable plastic. After use, it can be safely disposed of without producing any harmful substances. In addition, polystumin also has the same printing performance as traditional film. Therefore Application prospects. Application in the field of five clothing is in terms of clothing
2. Can be made into gauze, fabrics, fabrics, non -woven fabrics, etc., with infection and biocompatibility. The fabrics made with silk -like luster and feel. , Don’t stimulate the skin, it is comfortable to human health, comfortable to wear, especially suitable for underwear and sportswear
In recent years biomaterials such as PLA have entered the packaging industry with great force. They become films that offer more environmentally friendly solutions. Films made from these types of biomaterials have been improving their transparency and performance against the demands of traditional packaging.
Films that are to be converted into packages must normally be laminated to obtain a more secure and higher barrier packaging thus better protecting the product inside.
Polylactic acid (PLA EF UL) is used in the manufacture of laminates for all kinds of applications: windows in breadstick bags, windows for cardboard boxes, doypacks for coffee, pizza seasonings with Kraft paper or stickpacks for energy bars, among many others.
The material properties of PLA makes it suitable for the manufacture of plastic film, bottles and biodegradable medical devices, including screws, pins, plates and rods that are designed to biodegrade within 6 to 12 months). PLA can be used as a shrink-wrap material since it constricts under heat.
PLA is classified as a 100% biosourced plastic: it's made of renewable resources such as corn or sugar cane. Lactic acid, obtained by fermenting sugar or starch, is then transformed into a monomer called lactide. This lactide is then polymerised to produce PLA. PLA is also biodegradable since it can be composted.
Coextruding PLA film has several advantages. With a core of high heat resistant type PLA and a low temperature skin, it allows for a wider processing window in most applications, while maintaining far more structural integrity in high heat situations. Coextruding also allows for minimal additional additives, maintaining better clarity and appearance.
Due to its unique process, PLA films are exceptionally heat resistant. With little or no dimensional change with processing temperatures of 60°C (and less than 5% dimensional change even at 100°C for 5 minutes).
Because it uses less energy to produce the PLA pellets. Up to 65% less fossil fuel and 65% less greenhouse-gas emisions than when making traditional plastic.
PLA plastic offers more end-of-life options than any other material. It can be physically recycled, composted industrially, incinerated, put in landfill and even recycled back into it′s orginal lactic acid state.
