For fresh milk, gable top cartons are widely favored as they reinforce perceptions of freshness and are associated with better nutritional qualities. Their improved recyclability align with consumer expectations for more sustainable dairy products.
Our gable top filling machines are designed for small to large scale milk processors. We offer a cost-effective FRESH configuration for fresh milk and fermented products, and an ULTRA CLEAN module for Extended Shelf Life (ESL) milk that minimizes contamination.
Our machines are compatible with locally sourced gable top packaging and support several formats (57x57mm, 70x70mm, 70x90mm, 91x91mm and 95x95mm). Please refer to datasheet for capacity per carton format.

Galdi supplied Greenfields Indonesia with gable top carton packaging lines for fresh milk.

At Galdi, we combine technological innovation with a unified vision and dedicated customer support.






Based on our global installations, dairy manufacturers typically achieve a shelf life ranging from 30 to 70 days using our ESL system. Note that the packaging/filling process itself does not “extend” shelf life, the equipment is engineered to significantly reduce the risk of recontamination.
The final result depends on several critical factors beyond the machine, including the quality of your raw milk, the specific timing and temperature of your pasteurization process, and the effectiveness of your CIP and SIP methods. Furthermore, maintaining a strict cold chain – from the cooling room through to distribution temperatures – is essential to ensuring your product reaches the maximum shelf life possible.
Galdi does not sell packaging directly. Instead, we provide an “open system” that gives you the total freedom to source gable top cartons from your preferred local or international distributors. Because our machines are compatible with different suppliers – provided you maintain the same cap and carton configuration – you have the strategic advantage of selecting partners based on the best balance of quality and price. This flexibility allows you to foster healthy competition between suppliers, ensuring your production remains as cost-effective and competitive as possible.
Yes, our machines are highly adaptable and can be configured to handle various liquid dairy products and multiple carton sizes. While switching between milk types requires a brief rinsing period to ensure purity, the system is designed to keep this transition efficient.
While traditional UHT offers an extended shelf life, it often involves intense heat that can impact the nutritional value and taste of the milk. Galdi’s ESL solutions prioritize a fresher, more nutritious product, but we also offer a unique hybrid solution for maximum versatility. Some dairy manufacturers choose to process milk through a UHT sterilization system and then fill it into Gable Top cartons using our ESL machines. This approach allows you to offer a longer shelf life while benefiting from our machine’s ability to handle different formats on a single filler – a significant advantage over Aseptic machines, which are typically restricted to one specific format per line
Galdi offers a versatile range of machine sizes tailored to your specific production needs, with capacities ranging from 3,000 to 14,000 cartons per hour (cph). A key advantage of our technology is the ability to adjust production speed directly through the HMI panel. For instance, a machine with a maximum capacity of 3,000 cph can be adjusted to run at 1,500 cph or any speed in between. This flexibility allows you to scale your output and manage different production volumes efficiently using a single piece of equipment.
