Link to HYF
Q: What is PLA?
A: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.
Q: Are bio-based plastics, PLA, and degradable plastics all the same thing?
A: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.
Q: Are all degradable plastics the same?
A:No. There are two distinct sets of materials involved in the degradable question.
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.
Q: Why is HYF film made from PLA better than conventional petrochemical-based polymers?
A: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.
Q: How much plant material is required for PLA?
A:100 bushels of corn are equal to 1 metric ton.
Q: Will HYF plastic film degrade on shelves?
A:No. HYF will not degrade on shelves and has a similar shelf-life to other petroleum based plastics.
Q: How can HYF packaging film be disposed of?
A: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.
Q: Can I get a sample of Evlon Compostable Plastic Film?
A:Yes. To request a sample, visit our "Contact Us" section and submit your request by .
Q: I have tried other PLA films with no success. Why would HYF be most likely to succeed?
A: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 packaging equipment.
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!
Q: Is the Thermal Stability better than other PLA films?
A: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).
Q: Does it need be treated for printing?
A:No need. It has been corona treated.
Q: What printing inks can be used (UV or solvent based)?
A:The printing inks is same as the printing inks you are using, UV or solvent based is ok.
Q: What is the storage conditions?
A:--- 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 original packaging.
Q: What is Shelf life?
A:Suggest that it is used within 12 months from the production date.
Q: How does HYF package the product?
A:HYF packages two ways, vertical (which is the usual manner of shipment.) and horizontal for some of our larger sizes. We have two sizes of paper cores, six inch (153mm) and three inch (76mm).
For vertical packaging, the roll is wrapped with film with corepads attached to the ends of the roll by inserting plastic plugs into the core. The roll is then wrapped with thermal insulation film for protection.
For horizontal packaging the roll is wrapped with polyethylene film and set on fumigation-free plywood end boards. The rolls are then strapped to each other and to the pallet. Finally, each pallet is then stretched wrapped prior to shipment.
Q: How does HYF splice their product?
A:Q: How do I know how many splices are in a roll?
A:The number of splices is listed on the production label.
Q: What if I have a need for a special product?
A:If a customer has a special product need, HYF would take appropriate action after confirming and discussing the issue with the customer.
Q: How should the film be stored?
A:Heat shrinkable film is unlike other film substrates. You must take care that the film is stored at or below the temperature suggested to prevent premature shrinkage from occurring. Care must also be taken in storing the film after printing, and in shipping film to co-packers or end-users. Some natural shrink information is provided for you on each specification sheet. This goes for all shrinkable film.
Q: Are HYF films Corona Treated?
A:No. None of HYF's PVC, PETG shrink films are Corona treated. HYF film can be successfully printed without Corona treating. If you wish to Corona treat the film, please treat immediately prior to printing.
Q: What is the glues for PVC, PETG, PLA shrink film?
A:For PVC and PLA shrink film, the glue is Cyclohexanone
For PETG shrink film, the glue is 1.3 dioxane.
Q: Is your PVC shrink film cast or blown?
A:Our PVC shrink film is blown.

For PLA shrink film, the sampling fee and transportation need be afforded by your side.
Q: What is the minimum number of shrink sleeves I can order?
A:Small order could be accepted. However, due to the features of shrink films, reefer container is suggested to be used during the shipment.
Q: How shrink sleeve films be stored?
A:--- Please store it in temperatures above 30&#; (86°F) or below 10&#; (50°F)
--- Do not expose to rapid temperature changes
--- Do not store in direct sunlight
--- For mechanical, moisture and dust protection, store film in its original packaging.
Q: What are PVC and PETG?
A:Polyvinyl chloride (PVC) and Polyethylene Terephthalate Glycol-modified (PETG) are two commonly used shrink sleeve materials.
PVC &#; Easiest to control, generally the most cost-effective and offers good scuff resistance. Unit cost is less and it works better on some applications than PETG. There are two types of PVC &#; high shrink PVC and standard PVC.
PETG &#; Offers the best scuff resistance, has the highest percentage of shrink ability and easily recyclable. It&#;s also more stable and readily available. More customers are choosing PETG over PVC because it&#;s more readily available.
Q: How do I request a quote?
A:You can request a quote by speaking with us online or send emails. For a firm quote, it is better to provide us the type of film with detailed size and quantity.
Flexible PLA (Polylactic Acid) and TPU (Thermoplastic Polyurethane) are two popular flexible filaments, each offering distinct advantages and applications. While both materials are known for their flexibility and durability, they differ in terms of synthesis, physicochemical properties, and practical uses.
This article explores these differences, providing a detailed comparison to help you select the best filament for your 3D printing needs. Whether you're a hobbyist or a professional, understanding the nuances of Flexible PLA and TPU will enhance your printing experience and project success.
When it comes to flexibility, Flexible PLA offers a good balance between rigidity and elasticity, making it ideal for projects that require a certain level of malleability. On the other hand, TPU stands out for its superior flexibility and durability, making it suitable for applications where impact resistance and soft textures are essential.
In terms of print settings, Flexible PLA typically requires lower printing temperatures compared to TPU. While TPU is known for its flexibility, it can be a bit trickier to print due to its elasticity, requiring slower print speeds and adjusting retraction settings accordingly.
Pros and Cons of Flexible PLA
Pros:
&#;Ease of Printing: Flexible PLA is generally easier to print than TPU, with lower temperature requirements and less warping.
&#;Compatibility: Works well with most standard FDM printers without the need for significant adjustments.
&#;Versatility: Offers a good balance of rigidity and flexibility, suitable for moderately flexible parts.
&#;Strength: Flexible PLA can handle shape changes when pressure is applied, snapping back to its original form once the pressure is removed. This feature makes it different from regular PLA, which tends to be brittle. However, flexible PLA is not ideal for supporting weight as it tends to bend.
Cons:
&#;Durability: Flexible PLA is less durable than TPU and can become brittle over time, especially when exposed to UV light.
&#;Limited Flexibility: While flexible, it doesn't match the extreme elasticity of TPU, limiting its use in highly demanding applications.
&#;Hygroscopy: Flexible PLA is hygroscopic, meaning it absorbs moisture from the air over time. This moisture can negatively affect the filament's flexibility and print quality, causing issues like warping and surface defects. Proper storage is crucial to maintaining its properties and ensuring consistent printing results.
Pros and Cons of TPU
Pros:
&#;Superior Flexibility and Durability: TPU offers excellent elasticity and impact resistance, making it suitable for high-stress applications.
&#;Wide Application Range: Its toughness makes it ideal for automotive parts, protective gear, and other functional components.
Cons:
&#;Printing Difficulty: TPU can be challenging to print due to its elasticity, requiring precise settings and slower print speeds.
&#;Printer Compatibility: Not all 3D printers can handle TPU effectively without modifications or specific extruder setups.
When it comes to selecting the right material for your 3D printing projects, understanding the specific applications and use cases for Flexible PLA and TPU is crucial.
Flexible PLA, with its ease of printing and softer texture, is ideal for creating prototypes, wearables, and accessories that require a balance of flexibility and sturdiness. On the other hand, TPU's exceptional durability and elasticity make it a top choice for producing functional parts, protective gear, and impact-resistant components across various industries, including automotive, aerospace, and sports equipment manufacturing.
Flexible PLA
