Most customers are hesitant to make the decision to buy a fully automatic stretch wrapping machine due to the extremely high cost compared to a semi-automatic stretch wrapping machine. Comparing the final results, they are very similar. So what are the advantages of an automatic stretch film packaging machine compared to a semi-automatic stretch film packaging machine and how to justify a high investment.
Semi Automatic Stretch Wrapping Machines
If you are managing low volume applications, a semi-automatic wrapping machine may be the best solution for you. The machines require an operator to place the pallet loads on the stretch wrap and apply the film tail to the load to initiate the cycle. After that, the stretch film applies the film and wraps the pallet load.
These systems are generally used in low volume applications with less than 35 charges / hour. The purchase of stretch film is easily justifiable.
High Profile Machines
This machine is designed specifically for forklift loaded applications. Compared to low profile turntable stretch wrappers, this turntable offers easier access to loading and positioning as it is raised.
Low Profile Machines
Ideal for pallet truck operations; these machines are designed with the turntable positioned less than 3 inches from the ground. Using a ramp, pallet trucks can easily place loads on this series
Rotary Arm Machines
Designed for heavy or unstable pallet loads (light, high and poorly constructed loads), this type of bale wrapper makes it possible to easily wind up stationary loads on the ground. Three mounting configurations are available: wall mounting, floor mounting and pedestal stand.
Automatic Stretch Wrapping Machines
Automatic stretch wrapping machines require no operator intervention during the cycle. Loads are usually routed to the machine on a conveyor belt so that the machine can automatically start packing.
There are 5 specific function that a true automatic stretch wrapping machine be able to perform.
1. HOLD the tail of the film to start each stretch wrapping cycle,
2. WRAP the product based on the wrapping parameters,
3. CUT the stretch film from the pallet load and secure it in a clamp.
4. APPLY or SEAL the tail end of the stretch film to the load. To ensures that the hanging edge does not unravel during transit to the customer.
5. The ability to apply a Top Sheet (for Water proof or Dust proof) application.
We have a useful option on semi-automatic which allows to tear off the film at the end of a cycle, so that the operator does not have to cut the film. Although this is a useful feature.
There are also 4 basic types of automatic stretch wrapping machines. Here are some key features of each:
Rotary Ring:
The rotating rings are unique because they only rotate the carriage itself. With a compact design, this stretchable packaging is suitable for constant applications. The Phoenix PRRA Rotary Ring Pallet Wrapper dramatically reduces film costs as it can start and stop the cycle anywhere on the load. This concept offers high speed throughput (up to 150 charges per hour).
Conveyorized Rotary Arms
These machines eliminate the need to rotate the pallet in stretch packaging. Whether heavy or unstable loads, it can be packed quickly and efficiently with this system. Start and stop the cycle anywhere on the load. This concept offers a high flow speed (up to 110 charges per hour).
Conveyorized Turntable
This system offers a flexible and economical stretch packaging solution for up to 60 loads per hour with an optional capacity of 4,000 to 5,000 lbs (1.8 to 2.2 tonnes). Featuring a compact design,
Non-Conveyorized Automatic
Operators simply place the pallet on the wrapping machine and pull on the cord to start the automatic cycle. This machine eliminates the need for operators to get off the forklift to stretch the packaging pallets and is available for low profile, high profile and rotating arm operations.
