Pacmasta Constant Automatic Sealer 400mm -10mm Seal

Description

The 400mm constant automatic sealer from Pacmasta is a hands-free heat sealing machine built for businesses that need a steady, repeatable seal across a high volume of packaging tasks. With a 400mm sealing bar and a 10mm seal width, it suits operations where consistent output and minimal operator intervention are the priority.

Key Features of the 400mm Constant Automatic Sealer

• 400mm sealing bar: Accommodates a wide range of bag and pouch widths, making it suitable for small to mid-sized packaging lines.
• 10mm seal width: Produces a broad, secure seal that helps maintain package integrity during storage and transit.
• Constant heat technology: The sealing element maintains a continuous, steady temperature rather than generating heat in short impulses. This suits thicker or more demanding packaging materials that benefit from sustained heat contact, such as polypropylene and laminated films.
• Automatic operation: Once set up, the machine feeds and seals bags with minimal manual handling, reducing operator fatigue and improving throughput on repetitive tasks.
• Compact footprint: Dimensions of 480mm x 450mm x 380mm (L x W x H) allow the unit to fit comfortably on a standard packing bench without consuming excessive workspace.
• GST included: Pricing includes GST at the current applicable rate, keeping cost calculations straightforward.

Constant Heat vs Impulse Sealing

Understanding the difference between these two sealing methods helps with selecting the right machine. Impulse sealers heat up only when the sealing bar is pressed closed, which suits thinner polyethylene films and intermittent use. Constant heat sealers, by contrast, maintain an elevated temperature throughout operation. This makes the 400mm constant automatic sealer better suited to materials such as polypropylene, laminated films, and other substrates that require sustained heat to form a reliable bond. If your packaging material is thicker or you are running a continuous production cycle, constant heat is generally the more appropriate choice.

Typical Applications

The 400mm constant automatic sealer is well suited to a broad range of commercial and industrial packaging environments. Typical uses include sealing retail bags, food-safe pouches, parts packaging in manufacturing and distribution, pharmaceutical product bags, and any application where a clean, consistent 10mm seal is required at medium-scale volume. The automatic feed mechanism makes it particularly practical for businesses looking to reduce manual handling without investing in a fully integrated conveyor-fed system. It sits in a useful middle ground between a basic hand sealer and a high-volume band sealer.

Businesses with higher-volume requirements or a need for a longer sealing bar may also want to consider the Pacmasta Automatic Sealer 600mm, which accommodates wider packaging formats.
