When you are developing a new product, you have to determine how you will package it. There are numerous filling machines and filling techniques you can use. The challenge is finding the most efficient fill type for your liquid product. You want to find the method that saves you the most amount of time, money, and product. Additionally, you will have to consider the effect the fill type has on the final product appearance and your customers. Typically, manufacturers will choose one of three ways to fill their product: by weight, volume, or fill line. Read on to explore the differences between these three ways to fill your liquid product packaging.
Fill By Product Weight
When you fill the product by weight, the automatic filler machine will place a weighed amount into the container. There may be slight variances in container production, which would result in the product coming to a slightly different level with each container. However, every container will have the same amount of product. This can be especially useful in food industries where products are often sold and labeled by weight.
Filling machines, such as net weight filling machines that fill by weight, can be especially beneficial for filling bulk quantities. Additionally, they are suitable for filling products with a high value that must be weighed correctly to avoid profit loss.
Fill By Product Volume
When you set a liquid filling machine to fill your liquid product by volume, a set amount of liquid will be injected into the container. The amount injected is based on the physical amount of the product. When you fill by volume, your containers are generally filled to the same level, although the fill level may vary with packaging variations. However, the same quantity of product will be in each container.
Industries that fill plastic and glass bottles most often benefit from filling by volume. This can include companies that produce chemicals, cleaners, supplements, or pharmaceuticals. Pump filling machines and piston fillers are both standard machines that efficiently fill liquid products by volume.
Fill By Product Level
When you fill your product containers by level, your machine is programmed to fill each container to the same level. The product will be filled to that level regardless of the specific weight or volume of each container. This technique means that every container will appear to hold the same amount, which is good for bottles and jars that are clear and allow for a full view of the product. This can include cosmetics, craft beer, and other beverages. Customers don’t want to think that one bottle is fuller than another yet priced the same. Some customers may even believe a bottle has been tampered with if the levels differ from each container.
Filling by the product level creates a uniform packaging appearance and assures customers that every product is equal. An overflow filling machine can be used to fill a bottle to a specific, desired fill level. The unique nozzle of this filling machine enables exact filling.
