Bag in Box Inserters

Bag in Box Inserters

Bag-in-box inserters automatically open and insert pre-formed poly bags or liners into erected corrugated cases at rates up to 25 insertions per minute. Available in semi-automatic and fully automatic configurations, these machines handle gusseted bags, flat bags, and custom liners with adjustable box size settings.

Bag-in-box inserters automate the process of opening a pre-formed poly bag or liner and inserting it into an erected corrugated case. This eliminates the manual step of opening and placing bags by hand, improving throughput and consistency in packaging lines where products are filled into lined cases.

Insertion Process

The machine pulls a pre-formed bag from a magazine or dispenser, opens it using vacuum cups or mechanical fingers, and inserts it into the waiting case. The bag is positioned with the opening accessible for downstream filling equipment. Depending on the configuration, the bag can be cuffed over the case flaps for easy filling access or tucked inside the case for a flush fit.

Semi-Automatic and Automatic Configurations

Semi-automatic inserters require the operator to trigger each insertion cycle and may require manual case positioning. Fully automatic configurations integrate with upstream case erectors and downstream filling equipment for continuous, hands-free operation at higher throughput rates.

Bag Handling

These machines accommodate multiple bag types including flat poly bags, gusseted bags with side folds, and custom-shaped liners. Bag thickness, material, and size are matched to the product being packaged. The insertion mechanism is adjustable for different bag dimensions and case sizes without extensive changeover.

Anti-Static Poly Bags

Anti-static poly bags designed to prevent static charge buildup and protect ESD-sensitive electronic components during storage and shipping. Manufactured from polyethylene film treated with anti-static additives that dissipate surface charges. Available in flat open-end and reclosable configurations across standard mil thicknesses. Pink-tinted anti-static bags provide visual identification of ESD-safe packaging, while clear anti-static bags maintain product visibility.

Horizontal Form Fill and Seal machine for efficient packaging solutions.

Horizontal Form Fill and Seal

Horizontal form fill and seal machines wrap products in a continuous film web at speeds up to 200+ packages per minute. These flow wrappers form a tube of film around each product, create a longitudinal fin or lap seal, and cross-seal both ends for a fully enclosed package in continuous motion.
