China Supply 100% PLA Biodegradable High Transparent Films

The development of biodegradable plastics is a great and important innovation, because they can be broken down into harmless matters by microorganism when composting them or burrying them into the soil, so they can help to reduce our environmental impact.  They don’t need to be dealt with by incineration, thus they also help to reduce the number of greenhouse gases released into the air compared to regular plastics.

Just because of these, the PLA biodegradable products are becoming popular and popular, while the High transparent PLA biodegradable films are one of the important eco-friendly packaging products which many business will chose due to their excellent mechnical properties and high tranparency. 

Then how to choose the films which comply with environmental requirements?  The rel ated environmental certification will be crucial.
Theoretically speaking, the high transparent PLA films is 100% biodegradable and eco-friendly whether it is certificated or not.   Because the films are made from 100% PLA, while PLA is fully biodegradable itself.

But there may be someones sell fake high-transparent biodegradable films in the market, so the certificated PLA high transparent films will be very necessary.
Usually , the certificates to verify the films as biodegrdable and compostable films include EN 13432, TUV , DIN CERTCO, and so on.
Therefore, if the supplier can provide these certificates , then the films will be the ones you really need.

The main characteristics of PLA biodegradable film includes:

1. The films is sustainable and eco-friendly
The film is fully made from plant-based natural materials PLA , While PLA is usually derived from renewable resource , such as cornstarch , wheat, and so on. Also, it can be decomposed into CO2, H2O and organic matters within 6 months under composting, won’t release any toxic substances. So, It’s 100% biodegradable, compostable, sustainable ,and eco-friendly.

2. The film offers excellent transparency.
The film is made from 100% PLA , and is high transparent and food grade. These features make it very suitable for some applications that require high transparent packaging , such as flower packaing, food packaging , and some other packagings which require to show the contents inside the packaging bags clearly.

3. The film offer excellent mechanical and physical properties.
The film perform well in heat sealing and is flexible , these make it very suitable for making different types of clear packagings. Also , the film is water-proof and grease proof , especially when laminating with paper, the whole packaging can provide higher barrier performance.
In additon, the high transparent film can be used in e-cigarette，the oil-absorbing properties of the PLA high transparent film can effectively prevent oil leakage and condensate inhalation during the use of e-cigarettes, enhancing the user experience.

• The short answer is: yes.
• The longer answer depends on the type of plastic you compare it to.
• Bioplastics are generally more expensive than traditional plastics because they require extra steps in their production process and more material and energy consumption. This is why you won’t see any bioplastic products sold at a lower price point than their non-biodegradable counterparts.

Although both PLA and PHA are belong to bidoegradable plastic, there are some significant difference between them. PLA differs from PHA from preparation methods, physical properties, application fields and production costs.

Preparation method

Broadly speaking, both PLA and PHA are from the same raw materia,including cornstarch , tapioca or other renewable resources, but they are made by different preparation methods.  PLA (polylactic acid) is synthesized from lactic acid, while lactic acid are derived from starch. There are two preparation methods to make PLA, one is polycondensation of lactic acid, and another one is ring-opening polymerization of lactic acid after the synthesis of lactic acid and propylene glycol ester.       

PHA (polyhydroxyalkanoate) is synthesized by microorganismsby microbial metabolism.    To be specific , the starch are converted into PHA by microorganism.    So, PHA is biodegradable and degradable naturally without composting.

Physical Properties and Application Fields

PLA is biosafe and biodegradable, and also offers excellent mechanical properties, so it is suitable for being used in the packaging and textile industries.

PHA works well in biocompatibility and biodegradability, and both its melting point and strength are higher than that of LDPE, but its production cost is higher.  At present, PHA is mainly used as high-end biomedical materials, such as surgical sutures, drug carriers, and so on .

In addition, PHA works well in gas barrier performance and natural degradation properties, and can be degraded in soil, seawater, lake water, and living organisms.

However, both are thermoplastics that can be used in 3D printing to create strong and durable objects.

Production Costs and Market Applications

PLA is one of the most popular biodegradable plastics in the market because its production cost is lower relatively than that of PHA.   So they are gradually and widely used in packaging, textiles, etc.   In contrast,  PHA is less commercialized due to its higher production cost, and is mainly used as high-end biomedical materials.

In summary, PLA and PHA have significant differences in raw material sources, preparation methods, physical properties and application fields, and so on.  Each of them has its own unique advantages and application scenarios.
