NICHROME FILLING SYSTEMS FOR THE PACKAGING INDUSTRY

 


To put it simply, a pouch packing machine has two major components: the filling system and the bagging system. The filling system or filler is responsible for the accurate measurement and dispensing of the material into the pouch and the bagging system is responsible for packing and sealing the material in the pouch.

Whether it is a vertical form-fill-seal machine or horizontal form-fill-seal machine, the filler plays a crucial role in fast and accurateoperations. In the food industry, fillers are used for filling flexible pouches, cans, bottles, etc. In the pharma industry, filling systemsensure accurate and sterile discharge of the product into syringes, vials, capsules, sachets and bottles.

Depending on the type of product to be packaged, filling systems are selected. Liquid packaging or grain packaging, snack packaging or oil packaging, sugar packaging or ready-to-eat food packaging - different products require different filling systems. Factors such as container size, may play a part in selecting specific filling machinery, or in customizing the machinery, but there are two basic criteria packagers followwhen deciding which filling system to use for their product.

MAIN CRITERIA WHEN CHOOSING A FILLER

Level of automation: Filling machines or fillers are manufactured to work with automated packaging systems. They can also be manufacturedto work as stand-alone, semi-automatic machines, combining the filler with say, a capping machinery.

Knowing how many packs per minute, hour or day you need to fill will help to identify the level of automation necessary for your filling machine. High production levels may require an eight head automatic filling machine, and the filler could be designed to allow additional heads to be added in the future.

Filling principles: The unique trails or characteristics of the product to be packed determine the filling principle. The working of a milk filling machine will differ from a powder filling machine; an automatic sugar filling machine requires a different filler than what is used by an edible oil filling machine.

For example, gravity fillers areideal for thin, free-flowing products. Thicker, viscous products require more than gravity to complete the filling process, so a piston filleror pump filling machine is more suited to filling viscous products.

Packaging innovation to optimise your supply chain

Packaging is no longer limited to the pouch, box, strip or any other material that holds and protects the product. It’s an entire system of preparing products for safe, efficient and cost-effective movement throughout the supply chain.
Industry is now aware that packaging is not just the work of designers and marketing departments who focus on brand recognition and driving sales. Their emphasis is on developing packaging that grabs attention on crowded retail shelves.
With attention on driving sales and brand recognition, not much emphasis is placed on or trailer utilization of the package itself.
Packaging plays a crucial role in supply chain management. It affects the physical distribution of the package. Logistics demands packages that can be easily handled throughout all processes and by the consumer. Packaging also affects production, which prefers one size of packaging for all products to minimize time, material, and labor costs.
Package optimization makes the difference.
Package optimization is an activity that seeks to make the product’s packaging more supply chain friendly. By making small changes, packaging can be made more ergonomically and sustainable, saving time, material and money that can make a big difference to the company’s supply chain. This in turn, leads to maximized return on investment.
Product’s Packaging
Here are three basic ways to optimize your packaging:
1.Choose the right materials: It’s important to make smart decisions about the proper primary, secondary and tertiary packaging to help your product and its packaging navigate the different stages and environments it will travel.
Materials that are expensive or difficult to use could add time and money to your supply chain. The good news is, you can often reduce or change your packaging materials without compromising the quality of your product or the perception of your brand.
2.Think sustainability: Package optimisation is an opportunity to go green and promote sustainable business practices. You can find ways to use less material and/or find materials with reduced carbon footprint. This will help you save money and the environment — while enhancing your company’s image as an environmentally responsible corporate citizen.
3. Optimise shipment costs: When it comes to shipment from factory to retail shelf or consumer, the size and weight of your boxes impacts your logistics costs. Optimising your product package ensures you optimize the space and weight occupied in transportation and storage, so you can transport more products — saving both time and shipping costs.
How Nichrome helped saved millions with packaging optimisation
Nichrome, India is leading integrated packaging solutions provider recently came up with a small optimization idea that resulted in impressive benefits for its client. As an expert with over 4 decades in the business, Nichrome understands that the benefits of an optimized package are amplified throughout the distribution cycle.
Integrated Packaging Solutions
For a renowned milk producer and marketer in Pune, Nichrome suggested they alter the size of their milk pouch by a few millimeters, making it a rectangular shape. This minute change in the primary packaging not only makes the pouch stand out amongst the other square pouches in the market, it also means more SKUs can be fitted in a typical crate and further, more pouches in a truck. Besides the cost savings in packaging material, even greater savings have resulted from decreased handling, storage and transportation costs.
Conclusion
It’s not easy optimising your package. Ideally, companies should get their marketing, technical and logistics experts to collaborate and develop solutions that enhance efficiency, reduce wastage and lower shipping costs while protecting and promoting your product. Wasteful, environmentally damaging practices are unacceptable — both for business and the earth.
Partnering with a packaging expert like Nichrome can help. From pouch formats and packaging material for primary packagingsecondary packaging and tertiary packaging, Nichrome collaborates to add value and deliver the optimal solution.

Edible Oil Pouch Packaging Protecting Oil from Spoilage

India is one of the largest producers and consumers of edible oil in the world. In India, different varieties of edible oil are consumed, generally depending on the regional preferences and availability.

Filpack Servo SMD
According to a report by ICPE (Indian Centre for Plastic in the Environment), oil and fat are subject to spoilage due to effect of environmental factors that can affect their stability. Oxygen is the most critical factor affecting stability. The presence of oxygen leads to oxidation and formation of hydro peroxides and peroxides and then aldehydes and ketones resulting in off-odours due to oxidative rancidity. Oil containing high degree of unsaturated fatty acids such as safflower, soya and sunflower are highly prone to oxidative rancidity whereas oils with high degree of saturated fatty acids are less susceptible.

Another important factor which contributes to the deterioration of oil is moisture. Hydrolysis of triglycerides results in formation of glycerol and free fatty acids. Off-flavors occur due to hydrolytic rancidity.

In India, 52% of oil and fats continue to be traded in loose/unpacked form. Traditionally, oil and fats have been packed in 15kg square tinplate containers. However, today, other types of packages like plastic containers, lined cartons and flexible pouches are commonly used.

For edible oil packing, Nichrome is the preferred supplier of oil pouch packing machines. As a renowned, innovative Edible Oil Filling Machine Manufacturer, Nichrome is trusted for its cooking oil filling machines and ghee pouch packing machines that help protect the purity of the product, improve time-to-market, and enhance the retail value of the brand.

Sprint 250 Visco
Flexible pouches and modern automatic form-fill-seal packaging technology ensure that the contents are protected from oxygen, moisture and contamination. Other advantages of packaging oil, vanaspati and ghee in flexible pouches are that they are more economical, and easier to transport & shelve than any other available package. FILPACK SERVO SMD packs limited quantities of edible oil, vanaspati and ghee in flexible pouches of 1 kg, 500 g and 200 g capacity. The pouches may be in the form of pillow or stand-up pouches.
