40mic Transparent Eco- Friendly & Compostable PLA Film For
Packaging & Label
1. Production Description
If you’re an eco-conscious business, you’ll love our PLA films.
They’re completely biodegradable, are sourced from renewable
locations and are the most ‘green’ film we offer.
Of course, PLA is made from corn starch. To learn more about its
properties, get in touch.
Composting is a method of waste disposal that allows organic
materials to be recycled into a product that can be used as a
valuable soil amendment. PLA is made primarily of polylactic acid,
a repeating chain of lactic acid, which undergoes a 2-step
degradation process. First, the moisture and heat in the compost
pile attack the PLA polymer chains and split them apart, creating
smaller polymers, and finally, lactic acid. fungi and bacteria are
involved in PLA degradation. The end result of the process is
carbon dioxide, water and also humus, a soil nutrient. This
degradation process is temperature and humidity dependent.

5. Raw Materials
HYF sustainable packaging films are made of 100% PLA
More compostable and sustainable packaging is a key measure to ensure our future. The dependency on crude oil
and its impact on future developments made our team to widen its
view towards a compostable, sustainable packaging.
HYF PLA films are made of PLA resin which Poly-Lactic-Acid is
obtained from corn or other starch/sugar sources.
|• 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 microorganisms via a fermentation process;|
|• Lactic acid is polymerized and becomes poly-lactic acid (PLA);|
|• PLA is extruded into film and becomes flexible packaging;|
|• Flexible sustainable packaging is composted into CO2, water and biomass;|
|• Biomass is absorbed by plants, and the cycle continues.|
1) What is PLA?
PLA is a biopolymer made from plant-derived sugars that are
fermented and converted into lactic acid. The lactic acid molecules
then link to form rings called lactide monomers, which then link
together to create a chain of polylactide polymer.
2) Are bio-based plastics, PLA, and degradable plastics all the
No. PLA and other bio-based plastics are made from plant materials,
often corn. Not all bio-based plastics are degradable. Some
petroleum-based plastics can biodegrade. Degradable additives are
claimed to work in many resins. A degraded material is an
opportunity lost to reuse a valuable resource.
3) Are all degradable plastics the same?
No. There are two distinct sets of materials involved in the
One set of degradable plastics are materials such as PLA
(Polylactic Acid) that are unique plastics for which biological
degradation potential is part of the nature of the plastic.
The second set is materials of the standard #1 PET, #2 HDPE, #4
LDPE, #5 PP and #6 PS with special degradable additives included.
The mechanisms for degradation vary with additive type.
4) Why is HYF film made from PLA better than conventional petrochemical-based
Because less energy is used to produce the PLA pellets. Up to 65%
less fossil fuel and 65% less greenhouse-gas emissions than when
making traditional plastic.
5) How much plant material is required for PLA?
100 bushels of corn are equal to 1 metric ton.
6) Will HYF plastic film degrade on shelves?
No. HYF will not degrade on shelves and has a similar shelf-life to
other petroleum based plastics.
7) How can HYF packaging film be disposed of?
HYF 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
original lactic acid state.
8) Can I get a sample of Evlon Compostable Plastic Film?
Yes. To request a sample, visit our "Contact Us" section and submit
your request by email.
9) I have tried other PLA films with no success. Why would HYF be most likely to succeed?
What is different about HYF, is that it has an excellent heat seal
range, making it an easy transition from most OPP films on typical
With a range of 150 to 210°F (65-98°C), most heat seal machines
require the temperatures of the sealing bar to be turned down
considerably to produce a good seal, and another common change is
to reduce the dwell time as well to maximize seal strength.
A common mistake is to try to run it too hot. If there is
distortion around the seal and/or the film becomes brittle and
cracks or breaks at the seal, the sealing bar temperature is
probably too hot. Turn the temp down to make a better seal, and
save some energy in the process!
10) Is the Thermal Stability better than other PLA films?
Due to its unique process, HYF 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).
11) Does it need be treated for printing?
--- No need. It has been corona treated.
12) what printing inks can be used (UV or solvent based)?
--- The printing inks is same as the printing inks you are using,
UV or solvent based is ok.
13) What is the storage conditions?
--- Please store it in low temperature( 20℃);
--- Do not expose to rapid temperature changes
--- Do not store in direct sunlight
--- For mechanical, moisture and dust protection, store film in its
14) What is Shelf life?
Suggest that it is used within 12 months from the production date.
