Screw Caps & Lids

Your packaging shouldn’t be the thing that lets down the product you created to earn customers’ trust. With the right screw cap or lid, your product arrives intact, opens easily, and reseals reliably every single time.

With over 50 years of experience in the packaging industry, Ashland Container stocks and sources a wide range of screw caps and lid solutions designed for a secure fit, reliable sealing performance, and consistent results throughout a product’s lifecycle.

Screw Cap Materials Available at Ashland Container

The material your screw cap is made from directly impacts its chemical compatibility, seal quality, and shelf life. To ensure your satisfaction, Ashland Container is proud to offer the most widely trusted materials in the packaging industry:

Polypropylene (PP)

Polypropylene delivers excellent chemical resistance, a rigid structure that maintains its thread geometry under repeated use, and broad compatibility with food, personal care, and household products. PP caps are available in virtually any color and finish.

Polyethylene (HDPE & LDPE)

HDPE delivers strong impact resistance and a durable seal, making it a reliable choice for containers in the industrial, automotive, and chemical industries. LDPE is softer and more flexible, ideal for squeeze bottles where the cap needs to conform to the finish and reseal easily.

Aluminum

Widely used in the food, beverage, and pharmaceutical industries, aluminum caps are available as standard continuous-thread closures or as ROPP (Roll-On Pilfer-Proof) styles applied by capping equipment for enhanced tamper evidence.

Post-Consumer Recycled (PCR) Resin

These closures meet the same performance standards as virgin-resin caps while significantly reducing your product’s environmental footprint. This is especially important for brands with sustainability commitments.

Lined Caps

Many screw caps are paired with an internal liner to create a hermetic seal. ĐĄaps with foam liners (for cushioning and chemical compatibility), induction heat seal (IHS) liners (for tamper evidence and freshness), and pressure-sensitive liners, each suited to different products and regulatory requirements.

Types of Screw Caps & Lids Available

The right closure style depends on your bottle finish, your product, your industry, and how your customer opens and re-seals the container. Ashland Container carries the full spectrum of screw cap styles:

  • Continuous Thread Caps

    Continuous-thread caps feature a single helical thread that mates with a matching bottle finish (28-400, 38-400, 53-400, etc.) for a reliable screw-on seal. Available in flat, dome, and ribbed skirt profiles, from 18mm narrow-neck to 120mm wide-mouth lids.

  • Tamper-Evident Caps

    Tamper-evident closures include a breakaway band or shrink sleeve that provides visible evidence of first opening. Required in many food, pharmaceutical, and nutraceutical applications, these caps give consumers peace of mind that a product hasn’t been compromised before purchase.

  • Child-Resistant Caps

    Compliant with CPSC and PPPA regulations, child-resistant packaging requires a push-and-turn or squeeze-and-turn motion to open, making it a necessity for medications, supplements, and household chemicals while remaining easy to use for adults.

  • Wide-Mouth Lids

    Wide-mouth screw lids (typically 48mm and above, up to 120mm+) provide easy access to the product while maintaining a secure seal. Available in utility, tamper-evident, and lined configurations for food, industrial, and laboratory applications.

    ‍

  • ROPP (Roll-On Pilfer-Proof) Aluminum Caps

    ROPP caps are the premium standard for beverage and spirit packaging. Applied by a capping machine that forms threads directly onto the bottle, they deliver a tamper-evident hermetic seal and a clean metallic look. They come in standard and custom-branded formats.

  • Screw Guard Caps

    Designed for water and beverage containers, screw guard closures feature a built-in filter membrane or insert that controls the flow of liquid during dispensing while keeping the product protected during storage. Ideal for large-format water bottles and institutional containers.

  • Lined Metal Screw Caps

    For food products requiring an airtight, moisture-resistant seal, lined metal caps with lacquered or plastisol liners offer the combination of structural rigidity and interior protection. Common in sauces, preserves, and specialty food packaging.
