side ring pull bottle cap silver color

Detailed explanation of product structure

This product is a fully metal integrated easy to open structure, optimized for juice scenes

All aluminum cover body

Food grade aluminum alloy integrated stamping forming, standard 21 tooth crown structure. The aluminum layer can completely block oxygen, ultraviolet rays, and water vapor, effectively delaying juice oxidation browning, vitamin loss, and flavor deterioration, and the preservation effect is much better than that of tinplate and plastic caps; The cover surface is flat and smooth, supporting color printing, anodizing and other appearance processes, with a high-quality texture.

Integrated side aluminum pull ring

Made of the same material as the cover, aluminum alloy is integrated and stamped, with smooth and passivated edges for comfortable grip without cutting hands. Lateral opening conforms to ergonomics, without the need for tools or touching the drinking mouth with hands. The opening process is hygienic and clean, suitable for outdoor, commuting, catering and other ready to drink scenarios.

Precision prefabricated circular tear wire

The inner side of the cover is pressed with a continuous and precise depth circular easy to tear engraved line. When pulling the pull ring, it breaks along the engraved line in a regular manner, and the opening path is stable without small aluminum shavings falling off. The edge of the tear opening is smooth, avoiding scratching the lips when drinking, and the entire process is safe and debris free.

Food grade sealing gasket

Embedded inside the lid, it adopts a dual sealing structure of top seal and side seal. After capping, it tightly adheres to the end face and side wall of the bottle mouth, achieving the functions of gas locking, leakage prevention, and oxygen blocking; Optimize the odorless formula for juice scenes, without transferring off flavors, and maximizing the retention of fruit aroma.

Core product advantages

Compared to traditional tinplate juice caps

Stronger freshness locking ability: The all aluminum layer has a much better oxygen and light blocking effect than tinplate, effectively solving the pain points of juice browning and spoilage, and extending the product shelf life.

Experience upgrade: tool free side pull opening, replacing traditional pry open method, ready to drink, greatly improving consumer convenience.

Better acid resistance: exclusive acid resistant inner coating, long-term contact with fruit acid without corrosion, no odor, and better stability of juice flavor.

Compare plastic thread juice caps

Barrier crushing: The plastic cover has oxygen permeation issues, while the all aluminum cover completely blocks oxygen and light, significantly extending the shelf life of fruit juice and making it suitable for high-end fruit juice products.

High temperature sterilization: It can withstand pasteurization at 120 ℃, but the plastic cover is prone to deformation and odor at high temperatures, making it unsuitable for hot filling processes.

Stronger texture and anti-counterfeiting: The metallic texture enhances the product grade, and the tear and pull opening is irreversible. The anti-counterfeiting effect is far better than that of plastic caps that can be repeatedly tightened.

FAQ Frequently Asked Questions

What customized services are available?

Appearance customization: Aluminum cover in original color, matte, color spray coating, anodizing, supporting Pantone spot color matching.

Printing customization: Cover printing of brand logo, product name, production date, traceability QR code, marketing pattern.

Structural customization: fine-tuning of pull tab size, adjustment of opening force, customization of substrate thickness, optimization of tearing aperture (suitable for fruit pulp juice).

Gasket selection: PE/silicone/oxygen absorbing gaskets can be matched as needed, and can be customized according to food grade and environmental standards.

Packaging customization: Printing customer marks, brand information, export labels, and sanitary packaging specifications on the outer box.

What are the storage requirements?

Store in a dry, ventilated, and dark clean warehouse with an ambient temperature of 5-35 ℃ and a relative humidity of ≤ 70%.

Stay away from acid and alkali corrosion, high humidity, and odor sources to prevent oxidation of the aluminum layer and adsorption of odors by the gasket, which can affect the flavor of the juice.

The stacking height of cardboard boxes should not exceed 6 layers to avoid deformation of the lid and pull ring caused by compression.

Is it suitable for hot filling fruit juice? What is the maximum temperature that can be withstood?

fit. The all aluminum structure and acid resistant inner coating can withstand short-term high temperatures up to 120 ℃, fully compatible with 85-95 ℃ juice hot filling and pasteurization processes. The sterilized back cover does not deform, the coating does not fall off, and the seal does not fail.

Can using this lid for NFC freshly squeezed juice extend the shelf life?

Okay. The combination of all aluminum layer high barrier and oxygen absorbing fresh-keeping gasket can completely isolate external oxygen and absorb residual oxygen in the bottle, effectively delaying the oxidation browning and flavor decay of fruit juice. Compared with ordinary lids, it can extend the shelf life by 2-4 months, maximizing the preservation of the taste and color of freshly squeezed fruit juice.

Can carbonated fruit juice and fruit wine be used?

Okay. The bubble juice special product with thickened substrate is selected, with a pressure resistance of ≥ 0.7MPa, which can stably lock in carbon dioxide and store for a long time without bulging or leaking.
