High-Quality Acid and Alkali Resistant Sauce Packaging from China Suppliers | Boiling Packaging Solutions from Factory
Product Description
Sauce packaging fears leakage, boiled food packaging fears high-temperature deformation—traditional films often suffer from packaging damage due to insufficient corrosion resistance, liquid leakage due to low heat-sealing strength, or film surface shrinkage during boiling sterilization due to poor temperature resistance. Our high-functional IPE film integrates three core performances of "high-strength heat-sealing + acid-alkali corrosion resistance + wide temperature range tolerance" through multi-layer co-extrusion technology and special raw material formulation, providing a stable and reliable solution for sauce and boiled food packaging.
1
High-Strength Heat-Sealing: Reliable Protection Against Liquid Leakage
Using special heat-sealing resin and interlayer reinforcement technology, the film's heat-sealing strength is stably maintained at 20–25 N/15mm, far exceeding the industry's conventional standard of 15–18 N/15mm. Even when packaging thick sauces with particles (such as broad bean paste, beef sauce) or when internal pressure increases after boiling, the seal can still fit tightly without cracking or liquid leakage. Tests show that when the film bag containing sauce falls from a height of 1.2 meters or bears 5 kg of lateral pressure, the seal integrity rate reaches 100%, completely solving the leakage risk in sauce transportation and storage.

Acid-Alkali Corrosion Resistance: Suitable for Multiple Sauce Types
The film surface is added with chemical corrosion-resistant modifiers, forming a uniform protective layer through precision co-extrusion technology, which can withstand acid-alkali environments with pH 2–12 for a long time—whether it is acidic vinegar, tomato sauce, alkaline broad bean paste, or high-salt soy sauce and chili sauce, it can effectively block the penetration of sauce components, preventing the film from swelling, discoloration or strength attenuation. Even if the sauce is stored for a long time (more than 6 months), the packaging remains intact without affecting product quality and appearance.

Wide Temperature Range Resistance: Suitable for Boiling Sterilization Process
The raw material uses high-temperature resistant polyethylene substrate, which is subjected to special cross-linking treatment, expanding the film's temperature resistance range to -20℃ ~ 121℃: it can be used for frozen sauce storage at low temperatures, and can withstand 121℃ boiling sterilization at high temperatures (such as 10–30 minutes of boiling heating for prepared dishes). During the process, the film surface does not shrink or deform, and the heat-sealing strength attenuation rate is less than 5%. No additional protective layer is needed, directly adapting to the boiling packaging line of food factories, simplifying the production process and reducing packaging costs.

Safety Compliance and Efficient Processing: Balancing Practicality and Productivity
All raw materials comply with FDA and EU 10/2011 food contact standards, with no harmful substances precipitated during acid-alkali resistance and high-temperature resistance, and can directly contact food and sauces. The film surface has high flatness (thickness uniformity ±2μm), compatible with high-speed automatic packaging machines of 80–180 bags per minute, ensuring smooth conveying without jamming and reducing downtime for debugging. It also supports surface printing (adhesion up to 4B level), and can customize brand logos and product information, helping to improve the visual texture of packaging and enhance consumer recognition.
Frequently Asked Questions
Q1
What is the heat-sealing strength of the IPE film, and how does it compare to standard industry films?
Our IPE film maintains a heat-sealing strength of 20–25 N/15mm, which significantly exceeds the conventional industry standard of 15–18 N/15mm. This ensures the seal remains intact even under high internal pressure from boiling or physical impact during transportation.
Q2
What types of sauces is this IPE film compatible with?
The film is designed to handle a wide range of sauce types, including acidic products such as vinegar and tomato sauce, alkaline products like broad bean paste, and high-salt condiments such as soy sauce and chili sauce. Its corrosion-resistant layer withstands pH 2–12 environments without swelling, discoloration, or loss of strength.
Q3
Can this film withstand boiling sterilization at high temperatures?
Yes. The film is rated for use from -20℃ to 121℃, making it fully suitable for boiling sterilization processes lasting 10–30 minutes at 121℃. The heat-sealing strength attenuation rate remains below 5% throughout the process, and the film surface does not shrink or deform.
Q4
Is the IPE film certified safe for direct food contact?
Absolutely. All raw materials used in our IPE film comply with FDA food safety regulations and EU 10/2011 food contact material standards. No harmful substances are released during high-temperature or acid-alkali exposure, making it safe for direct contact with food and sauces.
Q5
Is the film compatible with high-speed automatic packaging machines?
Yes. The film's high surface flatness with thickness uniformity of ±2μm ensures smooth and consistent conveying on automatic packaging machines running at 80–180 bags per minute. This minimizes machine downtime and reduces the need for frequent debugging adjustments.
Q6
Can custom branding or product information be printed on the film?
Yes. The film supports surface printing with an ink adhesion level of up to 4B. Brand logos, product descriptions, and other information can be customized directly on the film surface, helping food manufacturers enhance packaging appearance and strengthen consumer brand recognition.
