    Flexible Packaging for Liquids: Puncture Caps and Couplings

    Packaging for Liquids That’s Clean, Reliable and Cost-Effective

    When your business requires safe and clean fluid dispensing, packaging safety and ease of use are essential. Flexible packaging for liquids extends the shelf life of whatever you’re distributing — pouches, bags and other product containers — which is why it’s essential.

    What’s even more essential is ensuring that your liquid packaging is built for efficiency, with puncture caps and couplings designed to make transfer and transport as easy as possible.

    Keep Liquid More Secure With Special BIB Packaging

    CPC Puncture Seal Caps for Flexible Liquid Packaging

    • Polypropylene and polyethylene for greater chemical resistance
    • Positive thread or snap-in seal with a 38mm fitment neck
    • Puncture seal membrane eliminates shipping caps and O-rings
    • Coupling body automatically breaks the membrane seal on the closure cap when connected
    • Stainless steel thumb latch to easily disconnect and connect

    The inside bag is created by sealing two layers of the desired film together and adding a leak-proof spout. Once the liquid is poured into the bag, it’s placed into the box. A dispensing spout or valve is applied to the bag, usually with a perforated hole for easy access to the spout. Each bag is specifically made to protect the liquid inside, ensuring that they are uncontaminated by the air outside. CPC offers a range of couplings and puncture caps to prevent air from entering the packaging when the liquid is dispensed.

    Liquid Dispensing Solutions From Fluid Management Experts

    CPC’s fluid management engineers are familiar with flexible packaging and its use for liquid and semi-liquid dispensing. With a strong emphasis on collaboration, CPC’s team works with packaging experts to determine the best fluid handling connection solutions to maintain quality, assure safety and deliver reliability. Our team — including materials scientists, design engineers and applications engineers — focuses on BIB and other flexible packaging connectors, resulting in a robust portfolio of quick connectors and couplings expressly for liquid dispensing.

    Safer, Easier Liquid Dispensing With Flexible Packaging Couplings

    CPC couplings instantly make connections to liquid dispensing systems from flexible packaging options, including Bag-In-Box containers. Our Puncture Seal dispensing system — which consists of a Puncture Seal closure cap and a specially designed quick disconnect coupling — is used to dispense virtually any liquid from flexible packaging. Offering different materials, including chemically resistant plastics, CPC flexible packaging couplings eliminate the need for shipping caps while making one-hand connection disconnection easy with a special thumb latch design.

    Trusted Reliability

    CPC quick connectors and couplings are designed to easily handle the wide variety of liquids that use flexible packaging containers. The user-friendly ergonomic design improves usability while the intuitive interface eliminates misconnections. With a thumb latch that ensures intuitive and rapid disconnections.

    Dependable Durability

    Built to help flexibly manage packaging for liquids, our connectors and couplings deliver optimized flowrates with excellent flow to size ratio for superior performance. CPC couplings feature a non-spill design to ensure mess-free, drip-free disconnects necessary for safe fluid handling in flexible containers.

    Overall Robustness

    Able to support a wide variety of flexible liquid packaging applications,  CPC quick connectors come in an expanding variety of sizes, termination options and materials including engineered polymers. A broad range of configurations are available to meet specific packaging requirements. With options being NSF-listed, CPC flexible packaging couplings are suitable for dispensing liquids, condiments or other food-based material. All CPC connectors and couplings are rigorously tested — including materials testing, product testing and torture testing to failure .

    Connection Assurance

    With a sleek body and ergonomic design, CPC connectors and couplings deliver single-handed operation with an audible click to assure users know when the fluid lines are connected. With a low force to connect, connectors make it simple to ensure a complete connection.

    Assurance of Supply

    CPC has a proven track record of providing products consistently under their stated specifications and quality requirements through having a strong supply assurance program. The program includes control of the manufacturing process from raw materials to final product manufacturing. Investments in extra capacity and redundant manufacturing ensure capacity when it’s needed. OEM customers have confidence in CPC’s ability to fulfill demand acquired by a track record of accurate lead times, identifying and communicating potential delays and, most importantly, by sound supply chain management.
