Remember the last time you picked a bag of coffee, chips, or even pet food off the shelf. Did you realize how tidy the packaging was? No spills or loose seals, but a perfect, ready-to-use bag.
One thing behind that perfect package is not only good design, but also strong technology: a premade bag packing machine. Premade bag packing machines ensure that products are safe, attractive, and fresh throughout the supply chain.
In 2022, the global packaging machinery market was valued at $46.4 billion USD, and it is growing quickly. One of the main agents of this expansion is the need for flexible, ready-to-use packaging, in particular, prepared bags.
What is this machine, then, and why should your manufacturing company purchase one? What are the different types? What should you consider when getting one? Let’s find out!
But first;
What is a Premade Pouch Packing Machine?
A premade bag packing machine is an automated multipurpose device used to fill and seal bags with various goods mechanically. These machines take ready-to-use bags, fill them with your product (solid, liquid, or powder), and then seal them shut, unlike form-fill-seal machines that create the bags on-site.
A premade bag packing machine is essential in sectors such as consumer goods, food, medicines, and cosmetics.
The machine is capable of handling various bag types according to their sizes and forms. It’s definitely one machine you’ll never go wrong purchasing for your manufacturing company.
And now;
Why Get a Doypack Packaging Machine?
A quiet, yet effective component of your brand success is packaging. It protects your product, ensures a longer shelf life, and provides the customer with a consistent experience, among other advantages.
So, here are five more reasons why you should get that doypack packing machine.
- Stability and Professionalism
First impressions matter. Suppose a client is picking up your product off the shelf and realizes that one bag is half-full, and another bag has been poorly sealed. That is sufficient to hurt brand loyalty.
A premade bag packing machine removes all these irregularities by making sure that all the bags are packed to the right degree and sealed accurately.
The result? Slick, consistent packaging that can make your brand look professional and trustworthy every time.
- Speed and Efficiency
Time is money in manufacturing. Packaging manually is a torturous process, and it can take hours to fill one bag and close it up. On the contrary, pre-designed bag filling machines are capable of filling dozens, and even hundreds of bags within a minute.
Such efficiency not only maintains pace with the customer demand, but it also provides the opportunity to expand your business without necessarily employing more individuals.
- Cost Savings
Yes, the initial cost of a machine might be terrifying. But think long-term. Automation in packaging saves you a lot of money in labor costs. It decreases the mistakes that cause product waste. It also saves you a significant amount of money by ensuring consistent sealing of the material, which reduces material wastage. Such savings accumulate over time.
- Versatility
Products are made differently; some are liquid, some powder, some granular. The beauty of premade bag packing machines is that it is versatile. These machines can package a variety of foods such as sauces, pet food, and ground coffee, with appropriate filler attachments.
Among the different categories of bags they are used to work with are gusseted bags, zipper bags, and stand-up pouches. One machine can be used to serve several product lines, which will give it the flexibility as your company grows.
- Safety and Hygiene
In the food and pharmaceutical industries, nothing can be done at the cost of safety.
But it’s impossible to prevent human contact completely, yet handling packages by hand increases the danger of infection.
The good thing: prefabricated bag packing machines automate the process of packaging and sealing goods without coming into close contact with one another, hence lowering this risk. This not only protects the customers but also makes your business in line with the strict health and safety laws.
2 Main Types of Premade Bag Packing Machine
There are two broad types of premade bag packing machines: rotary and horizontal.
They are available in various station configurations, which dictate the number of steps that can be completed in a single cycle.
Let’s unpack this.
Rotary Premade Bag Packing Machine
A rotary premade bag packing machine operates in a circular movement. The bags are put on the rotating platform, and they will proceed through a series of stations: bag loading, opening, filling, sealing, and finally, discharge.
For instance, they will take one of the premade bags, open the bag, and fill it with merchandise. As a last step, they will discharge the pouches after correctly marking and sealing them.
The design aids in keeping the production continuous, high-speed, minimizing the idle movement, and maximizing the throughput.
4 Key Features of Rotary Doypack Packaging Machine
This is what you should consider when choosing a rotary premade bag packing machine:
- Multistation configuration
There are rotary machines in four, six, and eight configurations. Four: is suitable for simple packaging and small-scale operations. The six-station setup incorporates giving (loading) the bag, coding, breaking open the bag, filling, sealing, and shaping. Clients with greater speed and production needs may also have an alternative to add two additional stations, thereby becoming an eight-station system.
- Quality of Materials and Control System
It uses 304 stainless steel for the frame, while food-grade stainless steel is used for the parts that will come into contact with food. In addition to being long-lasting, it can satisfy hygienic standards in delicate industries like food.
Although the system has a PLC touch screen to ensure easy use, one notable fact is that one cannot change the bag size automatically by using the touch screen.
The touchscreen is used to manage packaging weight, filling speed, and other key operating parameters, allowing you to exert precise control over the production process without complexity.
- Fast bag size adjustment
The adjustment helps save time when changing the machine. Instead of being made manually in a mechanical way, modifications are made through a touchscreen (PLC) interface. This efficiency is in particular handy when you are regularly changing bag size or format.
- Versatility is in-built
The rotary models can take powdered products (flour, milk powder, spices, etc.), granular solids (nuts, snacks, dried fruit), liquids or pastes (sauces, honey, shampoo), and even vacuum or gas-filled packaging (nitrogen, etc.).
Depending on the product and type of bag, the machine can also have attachments such as a multi-head weigher, vibration or hopper-vibration, unzipper, and side bag openers.
4 Advantages of Rotary DoyPack Machines
Rotary machines boast of:
- Speed and consistency
Packaging takes around 15 to 45 bags per minute, depending on the model and the product. This is determined by the size of the bag, weight, shape of the product (liquid, powder, or solids), and the number of stations used in the setup.
- The hygienic, lasting construction
The machine body is made of thicker steel (Eastern has that 8mm thick stainless steel is used in the frame, which is stronger than most competitors who use 5mm -6mm). This implies improved stability, reduced vibration, and reduced impact on film pulling or weighing precision. The feeding components are made of stainless steel as well, thus facilitating cleaning and sanitizing.
- The control system is up-to-date
PLC controller with a touch screen, auto-identification of errors (air pressure, temperature, bag mouth open, etc.), high sealing integrity, and simplified operation. These characteristics optimize manual management and shorten downtimes.
- Diverse product-bag compatibility
Has multi-layer composite film, single-layer PE or PP, paper bags, among others. The sizes of bags in the models available vary, e.g., width between 65-200 mm and up to 450 mm, length between about 160 and 500 mm, and a decrease in the speed with an increase in size.
Application
Take the case of a company in the nut and snacks industry that distributes the product around the country to supermarkets. The high demand would be met by a rotary machine of eight stations, while exhibiting consistency.
Horizontal Premade Bag Packing Machine
Horizontal premade bag packing machines move bags in a straight, linear direction. Bags are loaded onto a conveyor belt and transported through each station to be loaded. T
Bag placing/opening → filling → sealing → discharge.
Specialty pouches, such as stand-up doy-bags, zip-lock bags, spouted pouches, flat bags, irregular forms, and gusseted bags, are the greatest candidates for these machines.
4 Key Features of Horizontal DoyPack Machines
The following are some of the features that will assist you in assessing whether a horizontal machine is the right choice for you:
- Multi-position / multi-station models
Horizontal machines are available in single, three, six, and eight configurations. These machines are designed with multiple filling or working stations, which allow liquid or paste filling to be used in dual-output (or even triple) configurations. This gives flexibility and improved throughput.
- Flexibility of bag placement
Conventionally, a bag-placing apparatus typically flexes to accommodate different bag lengths, profiles, and even irregular pouches. It allows for a wide variety of pouch designs to be worked with, with only a few changes in machinery.
- Adjustable weight or fill controls
The fill weight or volume is often adjusted with screw frequency controls, number of revolutions, or screen/touch screen interfaces. This enables greater control, particularly using powders or granular products.
- Extensive compatibility of pouch types
Some models can accept flat pouches, pillow pouches, zip-lock or zipper doy-bags, spouted pouches, irregular or odd-shaped pouches, M-shape pouches, and even vacuum pouches. This comes in handy in case you have product lines with different styles of pouches.
4 Advantages of Horizontal Premade Packing Machines
Choose horizontal machines as they offer:
- Flexibility and light treatment
Horizontal machines also require premade bags that are inserted on the side of the bag rack, where they are automatically picked to be filled and closed.
Compared to rotary machines, horizontal packaging machines do not rotate but only move forward and backwards.
Should the customer want faster speed or packaging in dual material, we can come up with a dual-liquid pump out, and pastes will need a mixing machine to make the processing smooth.
- Speed vs. flexibility
These machines are not bad in terms of balance. They have the capacity to produce 5 to 65 bags per minute, depending on the pouch size, the nature of the fill (liquid or powder), and the bag size. That range will allow you to scale your output by being able to leave and also switch between bag styles and types of fill.
- Power, size, and footprint
Some of the sample specifications of Eastern are 1700x1050x1100 mm to 3040x1650x1500 mm in size, 2.5 to approximately 5 kW power consumption, and air-consumption values. These provide you with a rough estimate of the space, power, and infrastructure of your plant.
- Full automation
It features auto bag feeding, automatic zipper opening, filling, date printing, auto opening, sealing, and more. Additionally, it includes options such as a pneumatic gun for cleaning the machine after use. These decrease manual interventions, downtimes, and enhance hygiene.
Application
A frozen food company storing sauces and ready meals would have good use for a horizontal eight-station machine to prevent leakage. Essentially, it’ll help meet high output needs.
4 Key Factors to Consider while Selecting a Premade Bag Packing Machine
There are many choices available in the market, and it can be challenging to pick the right premade bag packing machine. The good news is that it is much easier to know what to do once you pay attention to these four variables:
- Production Capacity
Production capacity is the first thing to consider. How often do you have to package the bags per minute to sustain demand in your business? For small companies, 20-30 bags per minute may be sufficient.
Medium-sized corporations typically require 50-80 bags per minute, while large-scale production companies generally need 100 or more. Remember, the larger your production ambitions, the more stations your machine will have.
With high demand, a rotary system is the right one for you to package at high-speed, high-volume, while still ensuring accuracy and quality.
- Product Type (solid, liquid, or powder)
Not all machines have the capacity to deal with all products. Candy, nuts, or pet food are good examples of solid products and are better suited to multi-head weighers, which can provide consistent portions in a short time.
Liquids, such as sauces, oils, or detergents, use pumps and sealing systems constructed to avoid leaks.
Auger fillers are also required in the meantime for powders like spices, flour, or protein mixes to ensure precision and minimize dust.
Checking your product with the machine is the key to efficiency, no wastage, and a running production line.
- ROI and Budget
There is no secret in the fact that premade bag packing machines are a serious initial investment. However, the long-term benefits are usually greater than the initial expense.
One can make an informed choice based on the return on investment (ROI). Imagine how much labor will be saved in a year, how much waste will be reduced in both product and material, and how faster the machine will bring about the pace of production.
For instance, a machine with a cost of $ 60,000 will save $ 40,000 a year in labor and waste, and will pay off in less than two years. From this perspective, the purchase is a strategic growth move, not an expenditure.
- Packaging Design specification
Lastly, you will be interested in looking at the packaging design specifications. Your packaging is not merely functional; it is a part of your brand. The machine you will purchase has to suit the appearance and feel that you desire your merchandise to exude.
Think about how large the bags you will use are and whether they would accommodate the material to work with (laminated film, kraft paper, or plastic bags), the size of the bags, and any other attributes like gussets, tear notches, or resealable zippers.
You can install your machine to suit your packaging needs, ensuring that your products are both beautiful and safely packed.
Conclusion
Premade bag packing machines are your great business partners. They range from the speedy rotary machines to horizontal systems, which are versatile.
The most appropriate step, however, depends on your production targets, product type, and design of the package. These will help you choose the machine that will suit the requirements of your company.
And so the big question is, are you prepared to choose a machine that matches your product?
Do not purchase just any machine; collaborate with a trusted packaging machine manufacturer that will provide tailor-made solutions to your specific needs.
