Packsize machine is a mechanical equipment used for automatic or semi-automatic packaging of products. It is mainly composed of a feeding system, a metering device, a bag making mechanism, a sealing device and a control system. Packsize machine usually uses a stainless steel body and food-grade plastic parts. It is suitable for a wide range of materials, including granular materials, powdered materials, liquid materials and solid block materials. The price is generally between $3,000 and $20,000, depending on different models and functions.

In terms of working mode, the packsize machine feeds the product into the metering device through a conveyor belt, and enters the bag making link after accurate weighing. The heat sealing mechanism completes the sealing according to the preset parameters, and finally outputs the finished product packaging from the discharge port. The packaging size range is usually 50mm×80mm to 300mm×450mm, which can be adjusted according to the characteristics of the product. The entire process can be accurately controlled by the PLC control system to achieve fast and continuous operation.

Packsize machine price analysis by material classification

Different material characteristics determine the structural differences and price ranges of packsize machines. The price differences mainly come from the metering accuracy requirements, anti-pollution design and special material requirements. The following are four prices of packsize machines suitable for different material forms.

The price of a packsize machine for granular materials is usually between $3000 and $10000. It uses a vibrating plate to feed and a screw to meter, with an output of about 40-60 bags/minute.

The price of a packsize machine for powder materials is higher, about $3500-$12000. It is equipped with a dust-proof design and a precision spiral metering device, with an output of 30-50 bags/minute, and requires an additional dust removal system.

The price range of a liquid packsize machine is $4000-$15000. It uses a piston pump or a peristaltic pump for quantitative measurement, is equipped with a drip-proof nozzle, and has an output of 20-40 bags/minute.

The packsize machine for bulk solids is the most complex, with a price of $5000-$18000. It has a multi-station manipulator and a visual positioning system, and an output of 15-30 bags/minute.

Comparison of packsize machine prices by structure

Packsize machines can be divided into three basic types according to different structures: vertical, horizontal, and rotary. The structure and applicable scenarios of each type are different.

The vertical packsize machine uses roll film to automatically form bags. It has a compact structure and small footprint. It is suitable for small particles, powders and liquids. The output can reach 80 bags/minute (depending on the specific materials and functions). The bag type is mainly back-sealed or three-side sealed, which is suitable for standardized product packaging such as snacks and condiments. The price range is $3000-$10000.

The horizontal packsize machine realizes complex packaging requirements through a horizontal conveyor system and customized forming molds. It can handle large-volume products and special-shaped items. The output is 40-60 bags/minute. Its core advantage is that it supports a variety of bag types (pillow, three-side sealed, four-side sealed, etc.), and can integrate additional functions such as punching and labeling. It is commonly used in baking, daily chemical and other industries. The price is between $5000-$15000.

The rotary packsize machine is highly efficient. Through multi-station synchronous operation (such as filling, sealing, and slitting in parallel), the efficiency is increased to more than 200 bags/minute. It is especially suitable for large-volume continuous packaging scenarios such as food and medicine. Although the equipment cost is relatively high, its modular structure facilitates flexible adjustment and can be adapted to regular products such as strips and blocks, significantly reducing the energy consumption cost of a single package. The price range is $10,000-$25,000.

Price difference of packsize machine classified by function

According to automation, it can be divided into semi-automatic packsize machine and fully automatic packsize machine. Semi-automatic models have a simple structure and rely on manual assistance, which is suitable for small-batch production; fully automatic models integrate intelligent control, are efficient and accurate, and are suitable for large-scale industrialization needs.

The price of semi-automatic packsize machine is relatively low, about $2,000-$6,000, and requires manual loading and starting. It has a simple structure and basic functions, with an output of 10-20 packages/minute, which is suitable for small-scale production.

The price of fully automatic packsize machine is $8,000-$30,000, which integrates automatic feeding, detection and packaging systems, uses industrial computer control, and can produce up to 120 packages/minute, with data traceability and remote monitoring functions. The food and pharmaceutical industries mostly choose fully automatic models to meet GMP standards, while start-ups can consider semi-automatic equipment to control initial investment.

Features classified by packaging bag form

Packsize machine is suitable for various types of packaging bags, including back-sealed bags, three-side sealed bags, four-side sealed bags, stand-up bags, zipper bags, special-shaped bags, etc., each with its own functional characteristics:

Back-sealed bags (middle-sealed bags): using back heat sealing technology, strong sealing, suitable for granular (such as nuts, candies) and powder (such as milk powder, seasoning) products, can effectively prevent moisture and leaks.

Three-side sealed bags: only the left, right and bottom sides are sealed, with a simple structure and low cost. They are often used for small-sized foods (such as biscuits, instant coffee), pharmaceutical tablets or small packages of daily chemical products.

Four-side sealed bags: fully sealed on all sides, with good pressure resistance, suitable for liquids (such as juices, sauces), pastes (such as skin care products) or easily oxidized products, and need to be used with liquid filling machines.

Stand-up bags: The widened bottom design allows for upright placement, making them easy to display on shelves. They are commonly found in beverages, pet food, and snacks (such as jelly and potato chips). They require stand-up bag forming and filling machines.

Zipper bags: Plastic zippers are built into the bag openings, which can be opened and closed repeatedly. They are suitable for products that need to be taken multiple times (such as freeze-dried food and tea). Zipper pressing devices are required.

Special-shaped bags: Unique shapes (such as heart shapes and bottle shapes) are achieved through die-cutting or special bag-making processes. They are mostly used for gifts and high-end cosmetics, and require customized molds to match the packsize machine.

Packsize machine parameters

The price of a packsize machine ranges from $3,000 to $20,000. The price depends on four factors: material properties (such as powder, liquid, or corrosive substances), equipment type (vertical or horizontal), automation level (semi-automatic or fully automatic), and bag complexity (ordinary three-side seal or special-shaped bag). The core rule is: models that handle special materials, fully automatic horizontal design, and complex bag capabilities are more expensive, but they bring increased production and long-term cost advantages. It is recommended to comprehensively consider the following when purchasing: current production demand and future scalability; special requirements of product characteristics for packaging; budget and investment return cycle.
