1. lt is recommended to store the product at room temperature (preerably 25°C±3°C) in a cool and dry place, sealed away from direct sunlight.
2. Custom formula could be jointly developed according to specific requirements.
3. The shelf life of compostable products is 12 months in general, which is affected by product thickness and storagecondition, lt is suggested to use up as soon as possible.
PHA Marine Biodegradable Straw Material (White) is a modified straw grade of PHA (Polyhydroxyalkanoates), composed by 100% PHA without other polymers. It can realize degradation under various composting conditions such as marine, soil and freshwater. It also has excellent properties, including heat resistance, strength and low-carbon production.
PHA Marine Biodegradable Straw Material (White) is suitable for straw processing, with the straw processing solution developed by PhaBuilder, to develop biodegradable straws with excellent properties of heat resistance, toughness, and strength.
Pellets - 25 kg/bag (aluminum foil bags)
When transporting and storing, the temperature should not exceed 80℃.
Storage conditions: avoid sunlight, store at room temperature, and keep dry and ventilated.
PHA Marine Biodegradable Straw Material (White) is 100% biomanufacturing, safe and non-toxic, and safe to contact with human body.
Unwrap the foil bag and use it directly. If stored open for a period of time, it is recommended to dry before thermal processing; Suggested drying conditions: 80℃, 6 hours.
