Types of air-tight sealing machines

The role of a food vacuum sealer machine goes well beyond just avoiding air exposure. Products like the ones below provide commercial enterprises with affordable sealing machine options that add to shelf life and profitability.

• Cap-lock sealers

  Cap-lock air-tight sealing machines achieve secure container sealing through die-locking caps. This unique design combines the cap's bottom part, which has a seal, with a counter-die on the container's neck. When the two parts lock together, the seal component deforms until it encompasses the container's neck and lip, creating a tight seal. The deformed part will generally return to its original shape after unlocking. As a rule, die-lock cap seals work better for containers with an engineered neck and lip.

• Induction sealers

  Induction sealer machines are mostly used for plastic and glass containers. They comprise a non-touch, thermal sealing method creating a seal by integrating a foil disc and aContainer. The process needs an induction coil and a power supply. Lately, fridges and freezer packaging have included plastic induction liners under caps. They seal but allow for some membrane passing. Upon capping a container, the coil energizes a magnet core, which emits an electromagnetic field that compels the liner to heat. No heat is given to the Container interior. Heat makes the liner contract and bond to the Container.

• Pressure sensitive sealers

  Most container types can use pressure sensitive sealers. They use the closure's pressure to deform the seal, which in turn, makes it come into contact with the container, thereby creating a seal. This is the most common container sealing method for plastics.

• Flexi-ble sealing machine

  This is a sealer that uses a flexible liner to seal Containers. Usually, it involves a rubber liner compressed against the Container by a force exerted in the liner by a vacuum. The vacuum is formed in the space between the Container and the liner, and the reflection of the rubber liner pulls back after the vacuum disappears, thus allowing the Container to come out.

Specifications and maintenance of air-tight sealing machines

Specifications

• Machine Size: The dimensions indicate the length, width, and height of the sealing device. For example, the compact air-tight sealing machine measuring 360*370*130mm is suitable for small workshops. The larger pneumatic sealing machine (800*540*650mm) may be more suitable for industrial use, fitted in assembly lines.
• Weight: The weight of the sealing machine affects the mobility of the equipment. A heavier machine will be more stable and durable when sealing but may be more difficult to move or replace. For example, a manual air-tight sealing machine weighs 8.5kg, whereas the large pneumatic machine weighs about 36kg.
• Power and Voltage: The power of the sealing machine indicates the power requirements, i.e., the machine's operating energy. It is usually indicated in watts (W). The sealing machine may run on different voltages, which determine if it is fit for home and industrial use. The manual sealing machine has a power of 70w and runs on 220v. Higher voltage ensures faster and more effective sealing.
• Suction Power: The suction power of vacuum sealers is indicated in kilopascals (kPa). This reflects the vacuum strength. The greater the suction power, the more air the machine is able to remove from the container. For example, a 1.5/2.5/3.5 kPa machine is able to extract air from containers to give an extended shelf life to products.
• Production Capacity: This refers to the production number per hour. This capacity affects productivity. For example, a manual vacuum-sealing machine produced 60-120 bottles/hour, but an air compression sealing machine with more power could produce 1,500 to 2,000 bottles per hour.

Maintenance

• Cleaning: Frequent cleaning of the machine helps to maintain it and keep it in working condition. Using a wet cloth to wipe the surface of the machine helps to clean residue from sealing and prevent it from becoming sticky.
• Lubricating moving parts: Lubricate moving parts regularly to ensure that the air-tight bottle cap sealing machine operates smoothly and effectively. Lubricating parts reduces wear and tear and ensures longevity.
• Electronics maintenance: Double-check the wiring connections on the machine from time to time. Ensure that there are no loose or corroded parts. This helps to ensure consistent sealing performance and prevent accidental electrical leakage.
• Short/long-term storage: If the air-sealing machine is not going to be used for a long time, store it in a dry and dust-free place. Keeping the machine covered and away from direct sunlight helps to protect it from damage. When not in use, it is also a good idea to detach any accessories or add-ons to avoid loss or damage.

Applications of air-tight sealing machines

The food and beverage industry makes extensive use of air-tight sealers, especially for jars and cups, since consumers are increasingly interested in product quality and freshness. Packaging perishable and non-perishable food items, including jam, jelly, peanut butter, pickles, tuned cups, smoothies, coffee, and other items. Gerdon paste sealing machines, which come in both automatic and semi-automatic models, are an illustration of this. Paste products in polyethylene terephthalate (PET), polypropylene (PP), polystyrene (PS), and polyvinyl chloride (PVC) cups can be sealed with these machines. Before sealing, vacuum sealing machines can also be used to remove the air from the container and create an even tighter seal.

Air-tight sealing machines for jars are versatile pieces of equipment that can also be used to package pharmaceuticals such as medicines, vitamins, supplements, moisturizers, serums, and other products. Depending on the material and cap design, air-tight sealing machines can extend the shelf life of these products by ensuring that the container is securely sealed. Reducing container-stored medicine's exposure to air, moisture, and other potential contaminants can enhance its efficacy and purity.

Chemical industries also make use of these machines, particularly in industries that package pesticides, herbicides, and other potent chemicals that require air-tight containers to prevent leaks or spills. Pesticides and herbicides must be securely packed to prevent air, moisture, and other environmental factors from getting inside the container and breaking down the chemical. As a result, every part of the chemical industry's supply chain, from production to storage to transportation, must be meticulously observed to guarantee that there are no leaks or spills. Air-tight sealers help ensure this by sealing containers before they are transported or stored.

Air-tight sealing machines are not limited to food and beverage, pharmaceuticals, and chemical industries. They are used in many other industries, including cosmetics and personal care, to package products such as creams, lotions, scrubs, masks, hair products, and other items in jars, tubs, and containers; seeds and fertilizers industry to package seeds, fertilizers, soil, and other agricultural products in bags, jars, and containers; and mining industry to package mining chemicals and other materials in containers that require air-tight seals.

These machines can also be integrated into production lines to provide continuous sealing at high capacities. Whether used in industrial-scale production facilities or artisanal food production, air-tight sealing machines remain essential to producer and consumer expectations.
