Harvest Freshness.
Engineered Barriers.
Our industrial-grade nut packaging is engineered to combat the primary enemies of bulk kernels: oxygen and moisture. We utilize high-barrier co-extruded structures to prevent rancidity and maintain the crunch of high-oil content nuts.
Lipid Oxidation Protection
Our metallized VMPET and ALU-foil layers block 100% of light and oxygen, preventing oil rancidity in macadamias, walnuts, and cashews.
Nitrogen Flushing Support
Precision seal-strength ensures 0% gas leakage during MAP (Modified Atmosphere Packaging), extending shelf life for up to 24 months.
Anti-Puncture Resilience
Toughened Nylon (BOPA) layers designed to resist piercing from sharp nut shells and withstand rigorous bulk export conditions.
Food Science
Technical FAQ.
Nut packaging requires more than just a bag. We solve technical challenges regarding oil migration, seal contamination, and aroma loss.
"Crispness Guaranteed"
Industrial Grade Barrier Solutions
How do you prevent the "oily" look on the bag exterior?
We use specific PE/Nylon inner liners with high grease resistance. This prevents oil migration from the nuts through the laminate layers, ensuring your branding stays pristine and non-greasy.
Can your zippers handle nut dust during filling?
Yes. We offer specialized "dust-proof" zippers designed with wider channels to ensure a secure re-seal even if fine particles or nut fragments are present in the zipper track.
Are the materials odor-neutral for sensitive flavors?
Absolutely. We utilize solvent-free lamination and food-safe inks that undergo organoleptic testing. This ensures no "plastic smell" affects the natural aroma of your walnuts or almonds.
Solving the Realities of
Export Logistics
Nut kernels are vulnerable to staleness and bag failure during long-haul shipping. At Sengelin, we provide the technical film structures needed to maintain premium quality from the factory to the consumer's hand.
"Our nuts are developing a stale odor before the expiry date."
Oxygen contact with fats causes oxidation. We use EVOH-enhanced barrier films that provide a near-zero OTR, locking in the natural taste and scent of fresh nuts.
"Bags are splitting at the bottom under heavy volume."
Bulk nuts put physical pressure on seals. Our Quad-Seal and Flat-Bottom designs feature reinforced ultrasonic welding to ensure 100% load-bearing safety.
"Packaging looks wrinkled and worn after shipping."
Vibrations cause "flex-cracking." We utilize specialized matte or gloss PET finishes with high-tensile strength that resist abrasion and maintain a premium retail appearance.
