How to Master Temperature Control in the Food Industry

Mastering the art of temperature control is akin to holding the key to unparalleled freshness and quality. With over two decades of pioneering expertise, Hydropac stands at the forefront of revolutionising cold chain logistics, offering bespoke temperature-controlled shipping solutions that go beyond the average.


The Science Behind Effective Temperature Control 

Temperature control isn’t just about keeping food items cold; it’s about ensuring they reach their destination in pristine condition. The global cold chain logistics market, valued at nearly $248.4 billion in 2020, is testament to the critical role of refrigerated packaging solutions. These innovations safeguard everything from fresh produce to biotech products, maintaining their integrity from farm to fork. 

Strategic Ice Pack Placement: The Cold Truth 

One of the most understated aspects of temperature-controlled shipping is ice pack placement. The effectiveness of an ice pack isn’t merely in its existence within the packaging but in its strategic placement. For optimal results, ice packs should crown the contents of an insulated box, allowing cold air to cascade down, thereby enveloping the products in a consistent chill. 

Simply put, ice packs should go on top of an insulted box so cold air drops to the bottom and keeps everything cold, ice pack placement can change the shipping time from 36-48 hours. When determining where to position ice packs within your packaging, consider this: the placement can be the critical factor that extends the duration for which your goods remain at the desired temperature. For the best results, ice packs should be situated at the top of the insulated container. By positioning ice packs at the top of the container, you create an environment where cold air naturally descends, enveloping your products from the top down. This simple manoeuvre not only maintains a consistent temperature throughout but can substantially prolong the longevity of the chilled environment.  

Temperature-Controlled Shipping for Various Food Types  

 With the rise of e-commerce and global trade, consumers now have access to a vast array of foods from across the world, making temperature control in shipping more crucial than ever. Hydropac offers innovative solutions tailored to diverse food types, ensuring that everything from the creamiest cheeses to the freshest fruits arrives in perfect condition. 

Dairy Products 

Dairy products, known for their high perishability, require strict temperature control to prevent spoilage and bacterial growth. For items like cheese, yogurt, and milk, temperatures must be kept between 2°C and 4°C. Hydropac’s solution: Freshpac, a range of insulated shipping liners and ice packs designed to maintain this narrow temperature range, even in the heat of summer. Freshpac solutions are perfect for artisan cheesemakers and dairy farms looking to expand their reach without compromising on quality. 


Seafood’s shelf life is notoriously short, and maintaining temperatures just above freezing, between 0°C to 2°C, is critical to preserving its quality and safety. Using Hydropac’s range, seafood shippers can take advantage of specially designed gel ice packs and vacuum-insulated panels that ensure the catch of the day arrives as if it’s just been pulled from the ocean, whether it’s being shipped across the country or across the globe. 

Meats and Poultry  

Similar to seafood, meats and poultry are highly susceptible to bacterial contamination if not properly handled. Hydropac addresses this with a comprehensive suite of cold chain solutions that include robust insulated boxes and ice mats, keeping meats at their required temperature of below 4°C. This precision not only extends shelf life but also meets the stringent regulatory standards set for meat transportation, making it a go-to for butchers and meat processors. 

Fruits and Vegetables  

Shipping fruits and vegetables presents a unique challenge: they must be kept cold enough to slow down decay, but not so cold as to cause freeze damage. Hydropac’s custom ice packs and insulated packaging solutions can be tailored to the specific needs of different produce, keeping them at their ideal temperature range of 1°C to 10°C. This customisation is especially beneficial for exotic fruits that might require a warmer temperature, ensuring they arrive at their destination bursting with flavor and nutrients. 

Chocolates and Confectioneries  

Nothing disappoints more than receiving a box of melted chocolates. Sensitive to temperature fluctuations, chocolates require a cool, dry environment, ideally around 18°C to 20°C. Hydropac’s innovative ice mats provide a consistent cooling effect without the risk of water damage, making them ideal for confectioners looking to ship their delicate creations even in warmer climates. 


Regulatory Compliance and Safety Standards in Temperature-Controlled Shipping 

The adherence to regulatory compliance and safety standards isn’t just a legal obligation—it’s a moral imperative. For companies like Hydropac, operating within the food, pharmaceutical, and medical supply industries, these regulations are the backbone of their commitment to consumer safety and product integrity. 

The Critical Role of Compliance 

Regulatory frameworks govern every aspect of the cold chain logistics process, from packaging and transportation to storage and delivery. These regulations are designed to ensure that temperature-sensitive products are handled properly, maintaining their quality and safety from origin to destination. For food products, this means preventing spoilage and contamination. For pharmaceuticals and medical supplies, it’s about preserving efficacy and sterility. 

Hydropac’s approach to navigating these complex regulations involves a multi-faceted strategy: 

  • Continuous Education: Staying abreast of the latest regulations and guidelines is essential. Hydropac invests in ongoing training for its team to ensure comprehensive knowledge of both domestic and international regulatory landscapes.
  • Quality Assurance Processes: Rigorous QA processes are in place to verify that all packaging solutions meet the necessary regulatory standards. This includes testing for insulation effectiveness, durability, and compatibility with the products being shipped. 
  • Partnerships and Certification: Hydropac collaborates closely with regulatory bodies and industry associations to ensure their solutions are not just compliant, but also at the forefront of best practices in temperature-controlled logistics. Achieving certifications from recognised authorities serves as a testament to their commitment to quality and safety. 


Protecting Consumer Safety 

The ultimate goal of adhering to these regulations and standards is to protect the end consumer. When proper temperature control is not adhered to, it can lead to spoilage and foodborne illnesses. In the pharmaceutical and medical sectors, it can compromise the effectiveness of medications and the sterility of medical supplies, posing significant health risks. 


Hydropac’s dedication to compliance ensures that every product shipped not only meets the legal requirements but also upholds the highest standards of consumer safety. This dedication builds trust with clients and consumers alike, reinforcing Hydropac’s reputation as a leader in temperature-controlled logistics.
