Vacuum packaging is a method of packaging that removes air from the package prior to sealing. This process significantly reduces the oxygen content inside the bag, which in turn slows down the growth of aerobic bacteria and fungi. It also prevents moisture loss, helping preserve the freshness, texture, and color of the product.
This technique is particularly effective in the food industry, where oxygen exposure leads to spoilage, discoloration, and nutrient degradation. By creating a low-oxygen environment, vacuum packaging extends the shelf life of meat, cheese, dried fruits, and other perishables, all while maintaining their sensory and nutritional properties.
High Vacuum Degree and Sealing Integrity
Linpack vacuum packaging machines achieve up to 99% vacuum, offering one of the highest vacuum levels in the industry. This ensures that oxygen and air are effectively eliminated, enhancing product preservation. The machines feature robust aluminum vacuum chambers and precision-engineered sealing systems to ensure air-tight packaging every time.
Rotary Vacuum System: High Efficiency Meets Compact Design
Models such as the MRZK series use a dual-rotary structure—one for filling and one for vacuum sealing—allowing continuous operation. This system drastically improves productivity, reaching speeds of up to 100 bags per minute while maintaining a compact footprint ideal for space-limited production areas.
Accurate Filling with Minimal Error Margin
Equipped with PLC and touch-screen control systems, Linpack’s machines allow precise control of filling weights and vacuum parameters. They deliver high accuracy (±1g), minimizing product waste and ensuring uniformity across batches.
Hygienic Construction and Durability
All parts in contact with the product are made from food-grade 304 stainless steel. The design ensures easy cleaning and maintenance, making the machines suitable for industries with strict hygiene regulations such as food, pharmaceuticals, and chemicals.
Oxygen Permeability and Barrier Materials
Standard PA/PE vacuum bags have an oxygen transmission rate of about 100 cc/m²·24h. Linpack-compatible machines support high-barrier bags made from EVOH or PVDC multilayers, which can reduce oxygen permeability to less than 1 cc/m²·24h. This dramatically extends shelf life, especially for oxygen-sensitive products.
Freezer Burn Prevention and Texture Retention
By eliminating air, vacuum packaging prevents surface dehydration and discoloration during freezing—commonly known as freezer burn. This helps retain the product’s original texture, taste, and nutritional value over time.
Smart Technology and Remote Monitoring
Linpack integrates IoT sensors and smart algorithms in its machines. This allows remote monitoring, predictive maintenance, and real-time optimization—reducing downtime and improving overall equipment efficiency(OEE).
Material Optimization and Sustainability
The machines are engineered to minimize film usage without compromising seal integrity. Features such as no-fill no-seal functions and adjustable bag length settings reduce packaging waste and operational costs.
Flexible Bag Compatibility
Linpack machines are compatible with a wide range of pre-made bags—stand-up pouches, zip-lock bags, three-side seal, four-side seal, and more. They support a variety of product forms: liquids, powders, granules, and solids. This flexibility makes them ideal for sauces, spices, snacks, meat products, and even hardware items.
Hygiene is a cornerstone of Linpack’s machine design. Each vacuum chamber and contact component is washable, and all machines meet global food safety standards. Safety features like temperature control alarms and no-bag no-seal functions reduce operational risks. Additionally, remote diagnostics and online service support minimize downtime and ensure continuous operation.
Linpack vacuum packaging machines combine cutting-edge vacuum technology, high-speed rotary mechanisms, smart control systems, and hygiene-centric designs. These features allow businesses to preserve product quality, enhance shelf life, increase production efficiency, and lower operating costs. Whether you're a small food processor or a large-scale manufacturer, Linpack machines provide the technology and reliability needed to stay ahead in today’s competitive packaging industry.
