The choice of packaging directly determines the shelf life, moisture safety and marketability of milled rice. Proper packaging selection is important during long distance shipping or export by ocean because it can lead to moisture pick-up or tensile tearing of the packages or lead to grain spoilage. Today's rice millers and exporters need to process thousands of metric tons per year, and a 1% loss caused by packaging failure can be a huge hit on the bottom line. While Biaxially Oriented Polypropylene (BOPP) laminated bags and Polypropylene (PP) woven sacks are both viable choices for commercial suppliers, the decision between them must be carefully made.
In storage, synthetic polymers are used to resist high tensile stress, rough handling and environmental exposure in industrial grains storage. There are two types of woven structures, BOPP and PP woven bags produced by leading Rice bags manufacturers for particular requirements for retail, wholesale and bulk transportation.
When assessing both materials, its important to consider the following: structural layer, weight capacity, puncture resistance and environmental durability under heavy stacking loads.
Polypropylene (PP) Woven Bags
They are made through extruding the polypropylene resin into thin tapes, then weaving them into circular loom pattern.
• Structural Integrity: Unlaminated PP bags have good tensile strength, and tear resistance which is suitable for storing heavy bulks (25kg to 50kg).
• Breathability: Micro gaps in the weave ensure that air flows through continuously, preventing build-up of heat inside the warehouse in dry conditions.
• Cost Efficiency: Low unit packaging cost which is the industry standard for institutional and government grain supply due to simple manufacturing.
BOPP Laminated Bags
BOPP bags feature an ultra-thin biaxially oriented polypropylene film reverse-printed and laminated onto a woven PP fabric base using an extruded polyethylene layer.
• Barrier Protection: Reverse printed BOPP film provides 100% barrier protection from ambient humidity, dust and pest infestation.
• High Definition Graphics: Supports photo-quality rotogravure printing, up to 8 colours for high quality branding which will not scratch when handled.
• Weight Variations: Applicable to consumer packs such as BOPP bags 10kg, BOPP bags 25kg etc.
When choosing between BOPP, and PP woven packaging, you need to consider the target market, transport time and branding objectives. PP woven sacks are good for heavy bulk loads and are relatively cheap, while BOPP bags provide excellent moisture barrier properties and high impact retail presentation.
