Material Guide
The wrong material means packs that tear or cost too much. Here is the short guide.
Stiff and crinkly, strong even when thin. For carrier bags, polybags and dry goods.
Tear-resistant and soft even when cold. For ice bags, mulch film and shrink wrap.
Glossy and clear, keeps food crisp. For crackers, bakery and salt.
PE with additives designed to break down faster. For brands cutting plastic waste.
What You Should Know
Four things buyers often overlook when choosing a plastics supplier - and only notice once the product reaches their customer.
Packaging touches the food your customers eat. Halal certification means the materials and process are genuinely traced.
Plastic is sold by the kilo but used by the sheet. Cheaper resin often yields fewer usable sheets.
Packaging that tears easily damages your name. Neat packaging makes a product feel more valuable.
Getting one delivery right is easy. Holding it through the fiftieth is what we have protected since 1987.
Do The Maths
An illustrative example for the same bag size. The exact figures differ per product, but the pattern holds: what looks cheap often yields fewer usable sheets.

Common Questions
Standard unprinted products start from sack-scale quantities. Custom-printed packaging usually starts at 50 kg per design because of printing cylinder setup.
Yes, and this is where we add the most value. Send product dimensions, fill weight and stacking method - we will recommend the most efficient material and gauge.
HDPE for strength at the lowest cost, LLDPE for flexibility and tear resistance including when cold, PP for clarity and crispness. Unsure? Send us a sample.
Standard products take a few working days depending on machine queue. New printing needs extra time for cylinders and colour proofing. We confirm the schedule upfront.
Our food packaging lines use food-grade resin, with an ISO 9001:2015 and Halal certified process. Certificates are available for your audit.
Yes. Our routine lanes are Jakarta, Bandung, Lampung, South Sumatra, Bengkulu and Jambi. Beyond those we use partner freight.
