Bag-in-Box Filling Machine Suppliers & Manufacturers

Bag-in-box (BIB) packaging consists of a flexible inner bag with a dispensing fitment (tap or spout), contained inside a corrugated outer box. When product is dispensed, the bag collapses inward, preventing air ingress — this bag-collapse mechanism extends product shelf life after opening compared with rigid bottles or jugs. The BIB format is used widely in: wine — 2L to 20L wine casks for retail and food service are a major application, especially in Australia, Scandinavia, and Western Europe; edible oil — palm oil, sunflower oil, and vegetable oil blends are supplied in 5L–20L BIB for food service and retail; fruit juice and juice concentrates — 5L–20L retail and food service; sauces and condiments — tomato sauce, mayonnaise, ketchup for food service in 3L–10L; dairy — cream, liquid butter, custard in food service BIB; water — spring water and purified water in BIB dispensers for offices and institutions. BIB filling machines fill the product through the fitment (filling through the tap or through the bag neck before fitment insertion). Non-aseptic BIB machines fill refrigerated products with a short shelf life or products with sufficient natural acidity. Aseptic BIB filling machines fill commercially sterile product under aseptic conditions into pre-sterilised bags, producing ambient-stable products with extended shelf life of 12+ months — used for tomato paste, fruit concentrates, dairy-based products, and soups.

BIB bags are supplied with fitments that include a tap for consumer dispensing (retail wine and juice), a cap for food service (operator uses a separate dispensing gun), or a sports cap for institutional water. Common fitment brands include Vitop (Smurfit Westrock), Scholle IPN (including the popular Aseptic Scholle fitment for bag-in-box), and standard generic Chinese-manufactured fitments for non-aseptic applications. Bag sizes range from 1.5L (small retail wine) to 1,000L (industrial aseptic BIB tanks). The most common sizes are 3L, 5L, 10L, and 20L. BIB bags are typically made from multi-layer flexible film including LDPE, EVOH barrier layer (for oxygen-sensitive products like wine and juice), and sometimes aluminium foil layer for maximum barrier. BIB filling machines are available in manual or semi-automatic configurations (for small producers), and fully automatic configurations (for large food-service and retail producers). Fully automatic machines handle bag loading, fitment insertion, filling, capping, and bag-into-box insertion at rates of several hundred bags per hour. For wine producers, a semi-automatic BIB filler (operator loads bags, machine fills and caps) is a common entry-level investment. When sourcing a BIB filling machine, specify: product type and whether aseptic filling is required; bag sizes to be filled; fitment types and brands; required production speed; whether existing box closing equipment is in place; and food-grade requirements.
