The Opti®4000 Shrink Packaging System "easy-to-use" automatic L-sealer is ideal for higher output requirements. With the addition of a shrink tunnel, it has a throughput capacity of up to 900 pieces per hour, thus matching demanding production requirements. Because its small footprint requires less floor space the Opti® 4000 is ideal for congested production arrangements. Match the Opti® 4000 with the Opti®1300 shrink tunnel for ultimate production.
