NAVKALA PLASTIC INDUSTRIES

Our Food-Grade Polypropylene (PP) Dual-Flapper Spice Closures are precision-molded packaging solutions engineered specifically for seasoning manufacturers, food packers, and spice exporters. Designed to fit automated bottling lines seamlessly, these caps offer dependable torque retention, high crack resistance, and consistent snap-lock functionality for everyday commercial and domestic kitchen use.

Key Features & Technical Specifications

• Dual-Action Dispensing:

  • Sifter Side: Multi-hole perforation engineered for even, controlled sprinkling of fine powders, granular seasoning blends, salt, and ground peppers.

  • Spoon / Bulk Pour Side: Wide opening designed to accommodate standard measuring spoons or high-volume pouring for bulk cooking.

• Material Integrity: Manufactured , BPA-free, 100% food-grade Polypropylene (PP). Chemically inert, grease-resistant, and resilient against impact during handling and container transit.

• Hermetic & Tamper-Evident Sealing Options: Designed with internal sealing beads and compatible with:

  • Induction Heat Seal (IHS) Liners: Foil liners provide tamper-evidence, airtight preservation, and leak prevention for global export shipments.

  • Pressure-Sensitive (PS) Foam Liners: Torque-activated barrier liners ideal for fast assembly on dry packaging lines.

• Aroma & Moisture Retention: Positive-lock snap closures produce an audible click upon shutoff, creating an effective barrier against atmospheric moisture, humidity, and volatile aroma loss.

• Standard Fitments: Available in industry-standard neck sizes including 38mm (38/400), 43mm (43/400), and 53mm (53/400) with continuous thread (CT) finishes compatible with PET, HDPE, and glass jars.

• Customization Options: Offered in standard stock colors (Glossy Black, Pure White, Vibrant Red, Forest Green) as well as custom Pantone matching and custom orifice sizing (fine mesh, medium sift, or coarse flake) for bulk OEM/ODM orders.

Primary Industry Applications

• Ground spices and spice blends (turmeric, cumin, coriander, garam masala, paprika)

• Dehydrated herbs (oregano, parsley, basil, thyme, mixed Italian herbs)

• Table seasonings (iodized salt, pink Himalayan salt, black pepper, garlic powder)

• Bakery and beverage toppings (cinnamon sugar, cocoa powder, sprinkles, nutritional yeast)

Precision Engineering in Controlled Cleanroom Environments

Our pharmaceutical closures, caps, and dispensing systems are engineered to meet the zero-defect standards required by modern primary packaging. Operating out of state-of-the-art ISO Class 8 (Class 100,000) cleanroom facilities, our production lines isolate the molding, assembly, lining, and packaging stages from environmental contaminants, particulates, and bioburden.

Engineered for durability and ease of handling, our Cap with Integrated Handle (Butterfly handle cap) delivers a reliable sealing solution for heavy liquid containers. By molding a reinforced carrying handle directly into the cap body, this closure provides superior load-bearing capacity without compromising seal integrity during transport, storage, or retail handling.

The precision-molded internal threads ensure a snug, high-torque fit compatible with standard neck finishes (such as 38-400, 45mm, and 63mm). Equipped with customizable liner options—including EPE foam, induction heat seal (IHS), and vented membrane liners—the cap prevents leaks, maintains internal pressure stability, and protects contents against moisture, oxidation, and contamination.

Its ergonomic loop allows consumers and commercial workers to lift, transport, and pour from containers ranging from 1 to 10 liters with one hand. Ideal for manufacturers looking to reduce bottle resin weight by eliminating side-molded jug handles, this closure delivers high functional utility, cost efficiency, and shelf appeal.

Our Peanut Butter Jar Caps provide a durable, tamper-resistant packaging solution designed to meet stringent food-contact and safety standards. Formulated to withstand oil migration from oily pastes and natural nut butters, these closures prevent leakage, oxidation, and contamination throughout global transit and retail display.

Whether used with PET, HDPE, or glass wide-mouth jars, the continuous thread (CT) profile ensures effortless opening and tight re-sealing for the end consumer.

Key Features & Advantages

• Food-Safe & Chemical-Resistant: Manufactured using food-grade, BPA-free PP or HDPE plastic, preventing oil weeping and flavor degradation.

• Ergonomic Ribbed Skirt: Textured exterior provides optimal grip for opening/closing and facilitates non-slip torque application on automated capping machinery.

• Versatile Liner Compatibility: Accommodates induction heat seal (HIS) foil liners for tamper evidence, pressure-sensitive liners, or EPE foam wadding for hermetic barrier sealing.

• High Impact & Crack Resistance: Withstands vertical stacking pressure during palletization and drops during transit.

• Customizable Aesthetics: Available in standard industry colors (red, white, black, yellow, brown) and custom Pantone matching to align with brand identity
