Flavor-wise, nuts are rich in unsaturated fat and prone to oxidation and rancidity when exposed to oxygen; non-vacuum packaging causes loss of nutty aroma. Rice will gradually lose its natural fragrance and turn stale with air penetration. Vacuum packaging removes residual oxygen, locking original fresh taste and avoiding off-flavor.
For shelf life, ordinary non-vacuum woven bags or sealed pouches only support 6–10 months storage. Vacuum packaging suppresses mold growth, pest infestation and lipid oxidation, extending shelf life to 12–18 months, greatly reducing product waste.
For import and export, long sea freight and high humidity in container easily trigger quality defects. Many countries impose strict food safety inspection standards. Non-vacuum packages face higher rejection risk due to mold and pest problems. Vacuum brick packs occupy less pallet space, cut logistics cost and meet international food import requirements.
High Made provides automatic vacuum packaging equipment for rice and nuts. The machine achieves high-precision weighing, stable vacuum sealing and brick-shaped forming. It adapts to multiple granular materials, supports CE certification and overseas electrical specifications. It helps factories and distributors stabilize product quality, pass customs inspection, reduce overseas return risks and boost competitiveness in global grain & nut trade.
