Overview
Recommended Products

Designed for 5-gallon water bottle production lines, it works in synergy with snap caps to achieve an absolute seal over the bottle neck through high-speed heat sealing. It serves as the critical inner line of defense against contamination, ensuring the original freshness of water quality.

Product Overview

This product is a specialized sealing film (commonly known as "aluminum foil film" or "sealing film") for standard 5-gallon bottle necks. It is an indispensable core component of the bottled water sealing system. We are well aware that beneath the sturdy protection of the snap cap, this film, which directly contacts the water, is the final and most critical barrier against leakage, oxidation, and bacterial intrusion. Utilizing multi-layer composite technology and food-grade safe materials, it features excellent tensile strength and heat-sealing performance. It can instantly and firmly bond with the bottle neck on high-speed production lines, forming a smooth, uniform, and robust sealing layer, providing comprehensive safety protection for your large water jugs from the inside out.

Core features and advantages of the product

Food-grade safety, pure protection

Direct contact safety: The inner layer is made of pure plastic such as PE that meets national food contact material standards, ensuring no precipitation or odor when in long-term contact with drinking water, and guaranteeing absolute water quality safety.

Multi-layer composite process: Typical structures (such as PET/AL/PE) take into account strength, barrier properties and heat sealability. The aluminum foil layer (AL) provides excellent oxygen and water vapor barrier properties, effectively preventing water oxidation and odor inhalation.

Ultimate sealing, reliable isolation

High-speed heat sealing compatibility: The film heat sealing coating is uniform, the activation temperature range is precise, and it has excellent compatibility with 5-gallon bucket necks (usually made of PP/PC material), ensuring a high quality sealing rate of over 99.9% under high-speed production conditions.

Strong and resilient puncture resistance: The base material features high tensile strength and puncture resistance. During the process of capping and subsequent transportation, it can withstand pressure without cracking, ensuring the integrity of the seal.

High production efficiency and smooth operation

The film rolls have undergone special low-static treatment, which reduces static adsorption and film drift during high-speed automatic film feeding and slitting, ensuring the continuous and stable operation of the production line and lowering the downtime rate.

Precise dimensions: The slitting width and diameter precisely match the standard bucket neck, with smooth edges free of burrs, ensuring accurate automatic labeling positions and complete coverage of the sealing area.

Consumer trust is directly visible

Perfect sealing appearance: After heat sealing, the film surface is smooth and flat, closely adhering to the bucket neck, without wrinkles or bubbles, giving consumers a professional and reliable first impression.

One-time destruction design: When consumers tear or puncture this film, its integrity is permanently destroyed. Together with the anti-theft ring of the snap cap, it forms a double anti-counterfeiting evidence, greatly enhancing consumer confidence.
