Overwrapping Machines

TM100 trailing edge seal overwrapper

Marden Edwards offers a complete portfolio of Overwrapping machines, otherwise known as cellophane wrapping machines. Ranging from low cost entry level machines to high speed integrated systems Marden Edwards has the Overwrapping solution suited to your need. Whether you are looking to overwrap to save production costs or to enhance your product's appeal, all Marden Edwards overwrappers produce the same high quality of wrap and have size change versatility built in. All Marden Edwards machines are straightforward to maintain and are very low cost to run.

For individual pack wrapping the entry level machine is capable of speeds in excess of 40 products per minute. The highest output machine in the range is capable of speeds up to 300 products per minute. Typically, the majority of individually pack wrapping applications lie in the 50 to 150 per minute band.

Speedy Size Changeover

Although all machines can changeover from running one size to running the next in under 30 minutes, the servo motor actuated machines in the Marden Edwards range can change size in under 5 minutes. A changeover time of 15 minutes is typical for most applications.

The position of the lateral seal of the overwrap is extremely important. It is sometimes required that the lateral seal appears on the trailing edge of the carton. Marden Edwards have machines in the range dedicated to this style of presentation and others where the seal is positioned on the base of the product. How far from the edge of the pack the seal is placed is also of importance and this can be adjusted on Marden Edwards machinery.

For multi pack wrapping the product collating and handling systems can often be as important as the overwrapper itself. Marden Edwards have developed collating systems that can accept as many as 750 cartons or 1500 pouches per minute.

Although originally known as cellophane wrapping machines, Marden Edwards overwrappers can wrap just as easily with a wide variety of heat sealable films and papers. Polypropylene is the most popular wrapping material but Paper, PVC, Polyethylene and the new corn starch based biodegradable films run equally as well.

Because Marden Edwards knows that every production line is different every machine can be designed to be either left or right handed for controls and to be fed from either side or the front. Site engineering standards are taken most seriously and a wide range of PLC and inverter types can be selected.
