Sachet Packing Machines

Automatic sachet filling and sealing machines fall into two primary categories: vertical sachet filling machines and horizontal sachet packing machines. Both types utilize a single roll of film, which is mounted on an unwinding station. This roll feeds a continuous sheet of packaging film through several tensioning rollers and a printer bracket, allowing for the application of single or multiple batch codes on the film.

The key distinction lies in their film-handling approach. Vertical sachet filling machines split the film into two parts, which are then rotated 90 degrees and brought together, forming sachets with four sides. These sachets are created by a series of equally spaced vertical sealing bars, with the number of bars determining the number of sachet lanes. The product is dosed into each lane before sealing and cutting. On the other hand, horizontal sachet packing machines fold the film in half to create the sachet’s base, which is subsequently heat-sealed. The front and back of the sachets are formed, and the product is dosed into them before sealing the top.

The vertical machines often incorporate multi-lane filling systems above them, while the horizontal machines typically use a single or twin-head filling machine. Sachet packing machines can be coupled with liquid or powder filling machines to accommodate a variety of products based on the desired packaging. You can customise our sachet packaging equipment to meet your specific needs by integrating it with other systems. This flexibility enables you to create bespoke liquid sachet filling machines or powder sachet packaging machines, among other possibilities.

The answer to this question depends on factors like speed, flexibility, and the nature of the product. Vertical sachet filling machines are engineered for high-speed production, capable of generating multiple lanes of sachets simultaneously. However, this speed often comes at the cost of flexibility. Vertical machines are limited in their ability to switch between liquid and powder fillers, unlike horizontal sachet packing machines, which can accomplish this transition with relative ease. Horizontal machines, on the other hand, excel in accommodating short production runs and a wide array of formats, as they require no additional tools to change sachet specifications.

In summary, if you require high throughput within a limited floor space, particularly for a single product type, a vertical sachet filling machine proves to be the optimal choice. However, if your operation involves short production runs, varying sachet sizes, and different product types, a horizontal sachet packing machine is the better option.

Automatic sachet filling and sealing machines are versatile and suitable for a wide range of products and industries. Examples include powdered items like table condiments, spices, protein powders, desiccants, additives, instant coffee powder, hot chocolate, and bakery ingredients, among others.

Sachet packaging machines are also well-suited for granular products like pet food and dry cereals. In the food and beverage industry, sachet packaging is commonly used for paste products such as ketchup, mayonnaise, oils, vinegar, honey, jams, salsa, and mustard. Liquid products, including beverages, yoghurt pouches, shampoos, conditioners, moisturizers, and lotions in the personal care sector, are frequently packaged in sachets. Additionally, various cosmetics like balms, and face and hand creams are often filled using sachet filling machines.

Sachets are typically sealed using heat-seal technology. The packaging film is passed over a heating element, such that a thin layer of the film is melted to create a seal that is both high-quality and hermetic to prevent contamination and leakage.

The material used for sachet packaging depends on the product being packaged and its manufacturing requirements. Some of the most common materials used are polyethylene (PE), polypropylene (PP), polyester (PET) and aluminium foil.

Even though sachets are designed to be single-use, it’s sometimes useful to be able to re-seal a pack, particularly when it comes to high-value items like saffron or non-perishable cosmetics and medical supplies. Autopack can help you to achieve this using a re-closable label or zip.
