The challenges of automating this type of product bagging are well beyond the capacity of many product manufacturers and even many contract packaging providers, which is why many are bagging by hand with costly manual labor. Most of the liquid products are in a cylinder-shaped container. The cylinder must be moved through a tunnel where it will be encapsulated in a thicker-than normal plastic film. That extra-thick film must then be cut and trimmed to the right form-fitting size with more robust cutting tools than would be needed with thinner films. Then the film-wrapped product must be heat-sealed into a fully formed “bag.” All the while, the cylinder product wants to roll around as conveyor belts move it through these bagging stages.
Without the advanced, precision equipment needed to do this type of bagging, the results can be disastrous. If a cylinder containing an aerosol gets stuck in the heat tunnel and explodes, the resulting fireball could hurt both people and the equipment. This is why a surprising number of manufacturers are doing the required bagging by hand or are paying the high cost of having Amazon do the bagging.
The equipment we use for this type of packaging comes from a world-class provider. A few key modifications to this equipment has allowed us to meet the stringent Amazon requirements for liquid product packaging as confirmed through independent laboratory testing, including a variety of drop tests and shake tests. These tests must be performed for each unique product container from a client after it has been poly-bagged, and the client then sends the lab results to Amazon for approval.
