We all know that vacuum packaging technology reduces oxygen levels by removing air, inhibits microbial growth and oxidation, and maintains product freshness during transit and storage. It offers outstanding safety, reliability, and airtightness, and is widely used in food, pharmaceutical, electronics, and other industries. Among them, brick-shaped vacuum packagers (e.g., for rice bricks and grain packaging) have become a popular choice due to their superior shelf-life extension and transport-friendliness. How can brick vacuum packaging boost output and cut costs? Is it right for your business? If interested, read on.
The principle of brick type vacuum packaging machine
Let’s take the ZB500 series brick-shaped vacuum packaging machine from EasternPack as an example. It is a vertical packaging machine with integrated vacuum capability, also known as a fully automatic hexahedron vacuum packaging machine with internal vacuum. It is divided into granule internal vacuum hexahedron vacuum (common granular materials such as rice, grains, pet food, yeast, nuts, roasted seeds and nuts, healthy food, etc.) and powder product internal vacuum hexahedron vacuum (common granular materials such as rice, grains, pet food, yeast, nuts, roasted seeds and nuts, healthy food, etc.).
The machine performs fully automated operations: feeding, weighing, bag forming, filling, shaping, vacuum sealing, cutting, and output—packing bulk granular materials into pre-measured hexahedral pouches. With high-speed packaging, the uniform brick shape allows easy cartoning, palletizing, or direct retail display.
The main application areas of brick-type vacuum packaging machines
Food Industry (rice bricks, beans, nuts) – Over 60% Market Share
Rice & Grain Packaging: Food manufacturers specializing in rice bricks use vacuum packaging machines to pack rice and grains into compact bricks. This vacuum sealing technology prevents oxygen ingress, extends shelf life, inhibits bacterial growth, and ensures hygiene. The highly automated system boosts efficiency and reduces labor intensity.
Pickles & Preserved Fruits: Some producers use brick-shaped vacuum packaging to prevent oxidation-induced discoloration/flavor loss during storage/transport. It also avoids moisture-related mold, preserving freshness and extending shelf life.
Medicine & Electronics – Rising Demand for Moisture/Oxidation Protection
Medical Dressing Packaging: Sterile packaging is critical for medical dressings. Brick vacuum packaging blocks bacterial contamination while reducing storage/transport volume.
Electronic Components: Sensitive to moisture, oxidation, and static, components benefit from vacuum-sealed brick packaging, which prevents air/moisture corrosion and provides anti-static protection—reducing damage and failure rates.
Market demand and driving factors
You may have noticed that the demand for Brick-style vacuum packaging is on the rise. There are two key factors behind this. First, e-commerce and cold chain logistics are booming. Take frozen fresh products purchased online by consumers, such as salmon and hairy crabs. In order to prevent moisture and pressure and avoid damage during bumps during long-distance transportation, they must use Brick-style vacuum packaging.
Second, consumer preferences have changed. Nowadays, most people are more and more demanding on freshness and shelf life when purchasing food. For example, the nut rice bricks you bought can be effectively isolated from the air through Brick-style vacuum packaging, which can keep the fresh taste of nuts to the greatest extent and extend the shelf life, meeting your demand for high-quality food.
Additional Growth Drivers
Under the current trend of green environmental protection, green packaging regulations are becoming more and more stringent. Many brands have begun to use Brick-style vacuum packaging made of degradable materials. This type of packaging not only meets the needs of vacuum preservation, but also meets environmental protection requirements, so it is very popular.
At the same time, food safety supervision continues to increase. On supermarket shelves, high-standard vacuum packaging can better prevent the growth of microorganisms and is usually preferred by consumers. Brick-type vacuum packaging is a top choice due to its good sealing and stability, which has strongly promoted the widespread application of high-standard vacuum packaging.
