Eco-stretch

All too often we see that customers are not using the correct film or not using all capabilities of a machine. As a result, it could be that the customers costs per pallet are too high and that the burden on the environment is unnecessarily high.

We are looking forward on advicing and helping you reach out to your customers with a high quality product that helps them achieve optimal protection during transport, reduce environmental footprint and achieve lower costs.

We assist you with the right knowledge so you can analyze and evaluate the customers situation so that you can help them become more cost effective and efficient.

Eco-stretch is a technology that helps you and your customers:

• Achieve good film econonomy
• Achieve adjustable wrapping
• Vary the film tension
• Save up to 40 – 50% of annual consumption
• Achieve better load safety
• Reduce carbon footprint by saving up to 3 times more on CO2 emissions.

Power Eco-stretch

Motor powered pre-stretch gives possibilities for a very good film economy.

• AFD ( Automatic Film Detection) Recognize the thickness of the stretch film and then configure the most economical pre-strech ratio for the film.
• For this system to function accurately and to deliver at the high level performance it is designed for, high quality film must be used.
• Possibility of very high pre-stretch with good film quality.
• With the motor it is possible to vary the film tension between high and low ratio.
• Low film tension is necessary when the palletised goods is sensitive, very light, has uneven sides, sharp edges or is considerably smaller than the pallet.
• Normal setting of gear change: approx 200-300%.
• Pre-stretch measured on the goods is to great extent determined by the set film tension and can be higher but is generally lower than the gear set.
• The most flexible system for diverse types of goods.

Explanation power pre-stretch unit

• The film feed is driven by a servo motor which is powered by DC current.
• The pre-stretching of the film is achieved between the two geared rollers.
• Seven or eight (depending of machine) different pre-stretch levels can be selected, up to 400%.
• Film feeding is set automatically from choosen value.
• The film type is automatically detected, from 15 – 25 my, cast or blown film.
• Film feeding is sensed by the dancing roller and set during the first second of the filmcycle. The dancing roller then moves and falls back to its normal position where it controls the film feeding motor to feed out the required amount of film.
• The pre-stretch unit on CTR 2000 is powered by the batteries and controlled by its own PLC.
