Stretch Wrap Machines
Since the middle of the twentieth century, companies have been slowly developing more efficient and economical methods for packaging and shipping their products. For many years, when products were stacked on a pallet, they were held in place by metal bands, rope, or tape. Though the processes were efficient, they didn’t have sufficient stability or safety. Through innovation and research, specialized equipment has been developed that makes the packing process easier, faster, and more efficient. This new innovative process envelopes a pallet in a coating of plastic that tightly and securely holds products in place, preventing loss or shifting.

Applications of Stretch Wrap Machines
The basic function of a stretch wrap machine is to automatically encase and wrap a pallet in stretch wrap. The process serves the multiple functions of keeping the product from shifting or falling and protects it from damage during shipping. Modern businesses rely on the bulk shipping of products to meet market needs. Stretch wrap machines have enhanced the process by providing a safe and secure method for shipping while ensuring the safety of products.
Initially the process of applying stretch wrap was completed by hand and proved to be inefficient since the wrap was not evenly applied. The manual hand method was time consuming and labor intensive. Stretch wrap machines have improved the wrapping process, making it faster, more reliable, and far superior to hand-applied wrap.
Notable Types of Stretch Wrap Machines
Stretch wrap machines come in several varieties, with each type providing different wrapping options. Regardless of the type, all of them securely and firmly place stretch wrap over the pallet to hold products in place. Of the many varieties, turntable, rotary arm, and horizontal are the most common types. A turntable wrapping machine has a flat round platform that rotates. As the table turns with the pallet on it, the stretch film is applied from a dispenser. The turntable method tightly seals the pallet by stretching the wrapping around.
Rotary arm stretch wrapping uses the same principle as the turntable method. Instead of the pallet being rotated on a platform, a rotary arm applies the stretch material as it moves around the pallet. The outcome of the process is much like that of the turntable method and forms a very tight and secure seal. The horizontal wrapping method is similar to placing small products in a bag. The stretch film is dispensed by a huge ring that envelopes the pallet by moving down from above it. Horizontal wrapping is an ideal method for completely packaging the pallet with a plastic coating.
Benefits of Using Stretch Wrap Machines
A company’s products are its income. Protecting and securing them is an essential factor in the profitability of a company maintaining continuing positive relationships with its customers. Packaging of products should be reliable and dependable. It is for these two reasons that stretch wrapping has become a vital part of shipping and packaging. When hand film became available for wrapping pallets, it was an amazing solution to shipping products. After several years of use and poor performance, hand wrapping of pallets was found to be inadequate. The solution to this problem has been stretch wrap machines that consistently, tightly, and firmly wrap products.
