Bag-in-bag system protects paper bags from the environment

The new bag-in-bag system quickly and reliably packs filled paper bags individually or in groups with a weather-resistant plastic film (photo). This protects the contents against moisture, dust, insects and other environmental influences during storage and transport. The bag-in-bag is easy to integrate into existing filling and packaging systems. The impermeable film keeps dust from escaping from the filled bags, and it prevents product losses. The films have thicknesses of 30 to 100µm, so material costs are low. The outer packaging in the paper bags does not require an intermediate layer made of polyethylene (PE), a fact that also cuts costs and increases filling performance, says the company. The highly efficient system is so reliable that ultrasonic welding of the bags is usually not necessary. The bag-in-bag is designed for inline packers with a capacity of up to 800 bags per hour. — Beumer Group GmbH & Co. KG, Beckum, Germany
