Recycled PP packaging requires more than a PCR percentage. Buyers should verify resin origin, food-contact suitability, odor and color control, mechanical performance, recyclability claims, EPR data, and supply stability.
Seaweed-based barrier coatings are emerging as a possible way to improve moisture and oxygen resistance in paper packaging. Buyers should verify barrier data, coating weight, convertibility, food-contact compliance, and recyclability before using them as a PE coating alternative.
Paper cutlery can reduce plastic use, but it only works when strength, grip, hot-food performance, coating choices, recyclability, and compostability conditions are reviewed together.
Paper tubes and cylindrical packaging are gaining attention in specialty coffee, but the decision cannot stop at a plastic-free claim. Buyers should verify the spiral-wound paperboard structure, liner and cap design, oxygen and moisture barrier needs, degassing conditions, and recyclability claims before switching.
As PPWR seminars and training sessions increase in Korea, exporters should first organize five practical data files: packaging weight, material composition, recyclability, label wording, and supporting evidence.
As PPWR moves from legal text into standards, tests and technical documents, Korean packaging suppliers need a practical package of recyclability evidence, material data, weight tables and compliance files.
Fully recyclable sleeves in dairy and food packaging are not just a label change. Material compatibility, sorting, EPR cost, consumer instructions, and sleeve-line validation all need to be verified together.
The UPM, Michelman and BOBST collaboration highlights a practical question for paper packaging teams: barrier paper must be evaluated through coating performance, converting conditions, food-contact evidence and recycling claims.
VTT and LUT’s F3 project shows how cellulose-based films and coatings could reduce plastic in paper packaging, but the commercial test is barrier performance, sealing, recyclability and machine compatibility.
Amcor’s AmFiber examples show how paper-based flexible packaging is moving into applications traditionally served by plastic film. The key questions are barrier performance, sealing, line compatibility and recycling claims.
