Drip Coffee Hanging Ear Bag Packaging Machine

The drip coffee hanging ear bag packaging machine forms, fills and seals coffee in a single continuous process using a roll of filter film. It is designed for coffee roasters and contract packers who need to move from hand packing or outsourced packaging to in-house automatic bagging. The machine handles coffee grounds and whole beans in a hanging ear bag format, ensuring consistent fill weight and a clean, professional appearance for retail or food service use. It runs on a single phase 220V 50Hz power supply and requires a clean dry air supply at 0.6 MPa.

Key Benefits

Runs coffee blends with varying particle size without bridging or blockage in the filling system, maintains consistent fill weight across batches with electronic scale filling, seals the bag with ultrasonic technology to avoid heat damage to delicate coffee aromatics, produces a narrow seal edge that reduces film waste compared to wide heat-sealed borders, allows one operator to manage the line after training instead of a hand-packing team, and supports quick changeover between different bag sizes and film types.

Scenarios

Coffee roasters packaging single-origin or blended coffee for direct-to-consumer sale, contract packers handling multiple coffee brands from one machine, food service suppliers preparing coffee for hotel and restaurant use, and small to mid-sized roasters scaling up from manual packing to automated in-house production.

Who for

Coffee roasters replacing hand packing with automated bagging, contract packers serving multiple coffee brands with short batch runs, food service suppliers needing consistent portioning for daily use, and buyers replacing an older machine that cannot handle coffee grounds without clogging.

Problems Solved

Coffee grounds bridge and jam in machines designed for fine powder or liquid filling, heat sealing damages the coffee aroma and can scorch the film, hand packing leads to inconsistent fill weight and high labor cost, manual bagging limits output below 30 bags per minute, and non-food-grade film risks failing safety audits from retailers or distributors.

Technical Features

Ultrasonic sealing with two sealing devices for a tight narrow seam, electronic scale filling with 0.1 g per bag accuracy, accepts nylon and non-woven filter film imported from Japan, plus PET and PLA biodegradable films, runs on single phase 220V 50Hz at 1.2 kW with air supply at 0.6 MPa, and supports quick changeover between bag formats.

Materials

Nylon mesh film imported from Japan, non-toxic, heat resistant and food grade, non-woven fabric filter film for opaque hanging ear bags, PET film for high clarity bags, PLA corn fibre film for 100% biodegradable transparent bags.

Process

Film unwind and bag forming, electronic scale weighing and filling, ultrasonic sealing by two sealing devices, cutting and discharge.

Quality Control

Filling weight checked against the 0.1 g per bag accuracy target during run-off, seal integrity inspected on the ultrasonic seam before the machine ships, food contact film verified as non-toxic non-bacteria heat resistant food grade material, machine test run with the customer's own coffee before dispatch on request.

Certifications

ISO, CE

Customization

Choice of 120, 140 or 160 mm roll width to match your bag size, seal length set at 50, 60, 70 or 80 mm, nylon, non-woven, PET or PLA film supplied to suit your brand and compostability claim, air compressor supplied with the machine where site air is not available, voltage and plug arranged for the destination market on request.

Comparison

Flat filter paper coffee bag machine: The drip coffee hanging ear bag machine handles coffee grounds without clogging, while flat bag machines are better suited for fine powder. Heat sealed hanging ear machine: Ultrasonic sealing avoids scorching and keeps the seal narrow, but requires an air supply. Manual packing: The machine replaces a hand-packing team and holds consistent fill weight, but requires a fixed footprint and trained operator.

Use Guide

Connect a clean dry air supply at 0.6 MPa and a single phase 220V 50Hz outlet, load the film roll matched to your chosen 120, 140 or 160 mm width, set seal length to 50, 60, 70 or 80 mm for the bag size you are running, enter target fill weight and calibrate the electronic scale with your own coffee, run ten sample bags and check weight and seal before starting the batch, clean the filling hopper between blends to avoid carry-over of aroma.
