Quick answer: A PE liner is a polyethylene bag inside an outer bag, such as a paper sack. For coconut sugar, the liner keeps moisture, dust and odours away from the product, while the paper bag gives strength. “Food-grade” means the liner material is suitable for direct contact with food under the rules of the target market. Buyers can ask suppliers for declarations of compliance for food contact materials.
Key takeaways – PE liners protect sugar from moisture and contamination. – Food-grade liners meet food contact material rules. – Good closure of the liner is as important as the material. – Declarations of compliance document food contact suitability.
Why use a PE liner?
Coconut sugar attracts moisture from the air. Paper alone does not stop moisture well. A polyethylene liner forms a barrier that slows moisture uptake, helping prevent caking during long sea transport and storage. It also keeps the sugar clean and separate from the outer bag.
What does “food-grade” mean?
Food-grade materials are made and tested so they do not transfer harmful substances or unwanted odours to food in amounts that matter. Different markets have their own rules. In the USA, food contact substances are regulated by the FDA. In the EU, plastic food contact materials must comply with Regulation (EU) No 10/2011. Suppliers of liners usually provide documentation of compliance.
What should buyers check?
| Topic | Question to ask |
|---|---|
| Material | Which type of PE (e.g. LDPE, LLDPE) is used? |
| Compliance | Is there a declaration for food contact in my market? |
| Thickness | Is it strong enough for handling and transport? |
| Closure | How is the liner closed: heat seal, tie or fold? |
| Colour | Clear or coloured liner? |
| Storage | How are liners stored before use? |
How should liners be closed?
The liner should be closed tightly after filling, for example by heat sealing or securely tying, so air and moisture cannot enter easily. A well-closed liner gives much better protection than an open fold. The outer bag is then sewn or sealed.
How should buyers handle lined bags?
- Inspect bags on arrival for tears or punctures.
- Store bags off the floor in a dry warehouse.
- Open only what is needed for production.
- Reclose liners on partly used bags.
- Dispose of or recycle packaging according to local rules.
Are there more sustainable options?
Some companies explore thinner liners, recycled-content materials where allowed for food contact, or mono-material packaging that is easier to recycle. Any change needs testing to make sure protection and compliance remain.
Why does packaging matter for quality?
Even sugar with perfect moisture at packing can cake if packaging is poor. Good liners and closures help coconut sugar arrive in good condition and stay that way through its shelf life, which market specifications often state as 24-36 months.
