Packaging Equipment for Molten Products

In the packaging industry, molten products generally refer to products that must be liquefied before they can be automatically packaged by filling machinery. Some examples of molten products would be candles and other wax products, some pastes and even some deodorants. When these products are put to use by the end user, they are in a solid, or at least semi-solid, state. Liquefying the products allows them to be placed into glass jars, tubes or other plastic containers for consumption.

Liquefying the products will normally involve raising the temperature of the product significantly. Due to the increased temperature, certain modifications will be made to different packaging machines, while other equipment will work just as well for heated products as for more typical liquids. Generally, the machinery and components that work with, or come in contact with, the product itself will need some modification, while those that encounter the product after it has been properly packaged and cooled will not require modification.

Pre-Fill Packaging Equipment

Pre-fill packaging equipment may include items such as loading turntables, unscramblers, rinsing machinery and other equipment to prepare bottles for the packaging process. It would take a very unusual project for these items to require modification, as they all perform their duties prior to the introduction of the product. So the same machinery that would work for just about any typical, non-heated liquid product would also work for molten products. However, many of these products are packaged into unique containers, such as glue sticks or uniquely shaped candle jars. Custom equipment may be necessary to handle the unique containers, but this will be due to shape or size of the containers, not the molten nature of the product.

Filling Machine

More than any other piece of equipment, the filling machine will be affected by the type of product or products being run. Molten products, as we have already noted, require heating prior to filling. Not only must the product reach a specific temperature or temperature range, but it must remain at that temperature or range throughout the fill. This means that the product must reach the temperature in the supply tank and maintain that temperature through the tubing, fill bar, nozzles and all of the other elements of the product pathway. If the heat is not maintained, the viscosity of the product will change, causing issues with the flow of the liquid, clogging of the nozzles and other problems that can lead to inconsistent filling and excessive downtime.

Conveyor System

Conveyor systems used on molten product lines may differ in a couple of different ways from systems used for non-heated liquids. First, the belting itself may be a heat-resistant type of belt, helping to prolong the life of the system and protect against spills and splashes. In addition, most packaging systems for molten products will also include a cooling conveyor, which will be found right after the liquid filler. The cooling conveyor, not surprisingly, allows the molten product to cool, often to its solid or semi-solid state. This is necessity for several different reasons. First, the heated product can have an effect on bottles, caps and other components. To move the product and container immediately to a capping machine, labeling machine or other equipment could affect how that equipment works. Allowing the product to cool allows and/or settle also allows the capping machines, labeling equipment and other packaging machinery perform consistently and reliably.

Second, immediately capping or otherwise manipulating the product may cause some liquids to settle unequally, cave or otherwise fill the container inconsistently. The cooling conveyor gives each container and product the time to settle and solidify in a consistent manner. These conveyor systems may include a fan cooling system to speed up the process or they may simply be designed to add an extended length of time between the filler and the next packaging component using a serpentine conveyor, vertical space or whatever other room is available for cooling.

Post-Fill, Post-Cool Equipment

The equipment that follows both the filling and the cooling of molten products may vary greatly, though almost all will include a capping machine and a labeling machine at the least. Other equipment could include coding machines, packing machinery, case tapers, pallet wrappers and more. Much like the pre-fill packaging equipment, once the molten product is filled and cooled, modifications based on the fact that the product is molten are highly unlikely. Again, any modifications will usually stem from unusual containers, bundling or packing.

Like with any packaging project, the best equipment for a molten product will be determined by examining every aspect of the project, from products to containers, caps, labels, production speed, space and more. Only after all of these aspects have been discussed can the perfect solution be discovered.

Four Big Benefits of Utilizing Packaging Machinery

One of the first thoughts to enter a packagers mind when discussing packaging machinery relates to speed. How many bottles per minute can that filling machine, capping machine, labeler or other piece of equipment produce? Will it be able to handle my daily, weekly or monthly output? But automatic and semi-automatic machinery offer more benefits than just added speed to a packaging process.

CONSISTENCY

One large goal of packaging a product for any business is to make that product attractive to customers and potential customers. Appearance does matter. For instance, hand filling a beverage can result in inconsistent liquid levels from bottle to bottle, while the use of an overflow filler can ensure that each bottle reaches the same level, adding to the aesthetic value of the product when it reaches the shelf. The same is true of placing labels with logos or nutritional information in a consistent manner. Hand labeling can result in wrinkled labels or misplaced labels, while using a labeling machine can ensure each label is applied in the same manner.

RELIABILITY

Using packaging machinery can also make the process more reliable than using a hand packaging process. For example, whether the beginning of the production day or the end, the capping machine will seal bottles or other containers in the same manner, removing the risk of loose caps resulting in spilled product. Even if a capper did not speed up the process, using packaging machinery for such chores can reduce cross-threading, over-tightening, repetitive motion injuries and other issues that can result from manually tightening caps. Returning to the liquid filler, not all packagers will want to fill to a level. A number of product packagers are looking to reach a specific volume of product in each container. Equipment such as gravity fillers and piston fillers offer a reliable manner of reaching the same volume with each cycle, a task much more difficult when filling by hand.

EFFICIENCY

Packaging equipment simply does not get tired after six hours of production. From fillers and cappers to conveyors, labelers and more, the equipment will perform at the same rate throughout the day. While manual labor may be necessary to provide bulk product, caps, labels and other components to the packaging line, the reduction of manual labor means fewer mistakes and less oversight. By constantly running the packaging process at the same rate of speed, packagers can better gauge daily production, lending to increased efficiency in the overall process.

OUTPUT

As alluded to in the opening paragraph, speed can be important to a packager. Sometimes production demand simply exceeds what can be put out on a daily basis using a hand packaging process. Automation in the form of packaging equipment allows for greater speeds whether using semi-automatic or automatic machinery. While not every company may completely automate their system, as production grows machinery may replace hand packaging for the slowest processes until complete automation can be reached.

While not every packaging process will require packaging machinery, there are benefits above and beyond added speed. Equipment can range from simple handheld equipment that can add consistency and reliability to complete packaging lines that can increase output many times over when compared with hand packaging processes. The key for any business when choosing packaging equipment is to analyze the needs of the specific project to accomplish the specific goals, whether it be one or all of those laid out above.

Something About Packaging Machinery

Packaging is used in wide ranges. There are many things need to be packed in our daily lives. But do you know how does a product pack? It needs packaging machinery.

What is packaging machinery? It is a machine which can complete all or partial packaging process for products. With the appearance of the packaging material and the development of the packaging technology, this machinery turned up to our lives. Since 1960s, new packaging material was instead of the traditional material. And the this type of machinery was with great change and revolution after the plastic using. What is more, the development of super market requires more for packaging. In order to guarantee the speed and the safety of the product transportation, containers was emerged as the times require.

The standardization and systematization of containers’ size leads the packaging machinery to improve and develop. There are many types of packaging machinery. According to different points it can be divided into many types. In terms of the using way, there are inner packaging and outer packaging. According to the packaging industry, there are food packaging, household chemicals packaging, clothing packaging and so on.

The process of packaging mainly includes filling, wrapping and sealing.

Packaging machinery has great influence. Firstly, using machinery to pack products can improve the productivity. It is faster than hand packer. For example, a candy packaging machinery can pack hundreds even thousands of candies in a minute while a hand packer just can pack tens of candies. Secondly, it can guarantee the quality of the packaging effectively. Hand packer can not guarantee the same scale of the products according to the demanding shapes and sizes. Thirdly, it can reduce the working strength and improve the working condition. Hand packers have to use up much power.

When they pack some heavy and big size products, they will use out their powers. What is more, this type of machinery can protect workers from what will have bad influence on people. Last but not least, it adapts to the demand of large-scale production. What is more, it satisfies the requirement of cleanliness and hygiene. According to some regulars, food and medicine are not allowed to be packed by hands because hands will pollute products. Of course, it can promote the development of related industries, such as crafts, equipments, electronics industry and so on.

The development of this type of machinery relate to many industries. Wish our enterprises go through every difficulty and let packaging machinery come to the rank of the world.
