Packaging Machinery Corrosion Prevention Guide: Types of Materials Prone to Corrosion and Scientific Maintenance Methods

As a company deeply rooted in the packaging machinery industry, we understand the impact of equipment wear and tear on our customers' production. In previous articles, we've discussed the factors affecting the lifespan of packaging machines and various maintenance methods. Today, we'll systematically outline the types of materials that easily cause equipment corrosion, along with corresponding scientific maintenance strategies, hoping to help you reduce equipment wear and tear and ensure stable production efficiency.     01. Which Materials Easily Damage Equipment? In the food industry, common materials like vinegar and brine, as well as in the chemical industry, sulfuric acid and sodium hydroxide solutions, are all acidic or alkaline substances with strong chemical properties. Once they come into contact with the metal parts of equipment, they easily react, causing oxidation and thinning of the surface, and in severe cases, even perforation. Seafood, pickled vegetables, and fresh fruits and vegetables, which contain salt and moisture, form electrolyte solutions when salt and water combine, greatly accelerating the electrochemical corrosion of stainless steel and cast iron components. Furthermore, organic solvents such as alcohol, ink, and paint cannot be ignored. They can dissolve rubber seals and plastic parts on the equipment, initially causing seal failure, and over time indirectly leading to corrosion of metal parts.   02. How to Maintain Equipment? To address the above risks, maintenance should focus on the following two aspects: Daily Maintenance: After operation, thoroughly wipe clean any areas that have come into contact with materials using a neutral detergent with a pH of 7-9 to remove any residual acids, alkalis, salts, or organic solvents. Regular maintenance involves weekly inspections of easily corroded parts such as the hopper, conveying pipes, and seals. If rust spots or signs of aging are found, treat them promptly with rust remover, followed by application of food-grade rust-preventive oil. Additionally, seals should be replaced quarterly to prevent material from seeping into the equipment and causing more serious malfunctions.   03. Other Maintenance Methods Of course, the most important is source control. If your material is corrosive, be sure to clearly inform the salesperson during the initial communication phase so that we can select more corrosion-resistant materials during the equipment design stage, such as 316L stainless steel or special alloys, and optimize the structural sealing scheme accordingly, reducing the risk of corrosion from the source. Furthermore, as we mentioned before: never buy used equipment indiscriminately. The material and usage history of used equipment are often unknown, and there may be hidden corrosion damage, structural fatigue, and material incompatibility with the machine. Putting it into use could lead to downtime or even safety accidents. In addition, environmental control is crucial. Production workshops must be kept well-ventilated and dry, with relative humidity controlled below 60%. Dehumidifiers or ventilation equipment should be installed when necessary to prevent equipment from being exposed to humid, high-temperature environments for extended periods, thus reducing the accelerating effect of environmental factors on corrosion. As a company specializing in packaging machinery, Longchuang always prioritizes the user experience of its customers. Regardless of the materials your production involves, we can provide customized material selection advice based on material characteristics and assist you in establishing standardized maintenance procedures.

Economic downturn: Should we still invest in smart packaging equipment

This is precisely an excellent opportunity for strategic procurement, provided that your decisions adhere to a strict rule—investments must precisely address the most pressing current issues and deliver quantifiable returns in the short term. Please do not view it from a "yes or no" perspective, but rather consider "why now" and "how to operate safely." Core logic: Economic downturn is a window of opportunity for negotiation and upgrading You can view the current market environment as a buyer's market: Better Pricing and Terms: Equipment manufacturers, including ourselves, are facing increased competition and order pressure. You have the opportunity to secure deals at lower prices than usual, along with extended payment terms, more favorable financing options, or additional services. Shorter lead times: With supply chain bottlenecks alleviated, you can obtain and deploy equipment more quickly, reducing the investment cycle. Prepare for Recovery: When the economy rebounds and orders suddenly surge, your production capacity and efficiency are already ready to seize market opportunities instantly, while your competitors may still be hesitant. You are not purchasing for "today," but investing in the "tomorrow" recovery. The key to decision-making lies in whether your investment is "anti-fragile." A sound procurement decision should make your business more resilient, not more vulnerable, during economic downturns. Here is your decision checklist: You should take immediate action if any of the following conditions apply (one or more): Your customers are squeezing prices: You need to reduce unit costs through automation to maintain profit margins. You are facing severe "labor shortages" or excessively high labor costs: intelligent equipment can replace repetitive tasks, ensure stable quality, and reduce reliance on human labor. Your packaging material waste is severe: smart devices (such as visual positioning and precision cutting) can optimize material usage, directly saving substantial consumable costs. Your production line lacks flexibility: the current equipment takes too long to switch between products, while orders for small batches and multiple varieties are increasing. Intelligent equipment can switch quickly and adapt to market changes. A key client has raised new requirements: for instance, the need to add a "one product, one code" traceability feature to the product, which must be implemented through smart devices. You should suspend investment if any of the following conditions exist: Your cash flow is tight: equipment procurement can severely impact the daily operational safety of the business. Your return on investment (ROI) cycle exceeds 24 months: In times of high economic uncertainty, the ROI cycle must be shorter and more defined. Your question is unclear: You simply feel "it should be upgraded," but lack clear data (such as defect rates, labor cost percentages, or switching time) to support the decision. "Safe Landing" Procurement Strategy for You: Start from the "pain points," not from "technology": Don't ask "What is the most advanced equipment?" but instead ask "Where is my biggest cost waste? Which step is dragging down overall efficiency?" Then procure the most cost-effective solution that addresses this specific issue. Pursue modularity and flexibility: Avoid procuring large, dedicated production lines. Prioritize modular solutions that can be implemented in phases and easily reconfigured. For instance, upgrading the labeling and palletizing stages first yields more tangible returns on investment. Request a detailed, fact-based ROI analysis: Work with your team or vendor to calculate the specific savings per month/quarter (labor, materials, energy consumption, reduced returns, etc.). This serves as the foundation for your decision-making. Exploring innovative cooperation models: Inquire whether it is possible to use rental purchasing, pay by production, or adopt a trial before purchase model. This can significantly reduce your initial investment risk and cash flow pressure. Finally, please change your perspective During periods of economic prosperity, procurement is for expansion; During an economic downturn, procurement is for survival and to consolidate competitiveness. A smart packaging device that can immediately reduce your operating costs, improve quality consistency, and make you more flexible in responding to small batch orders is not a cost, but a strategic investment that can help you "survive the winter and lead in the spring". If you are willing to share your industry, factory size, or specific challenges you face (such as high labor costs or severe packaging material waste?), I can provide you with more targeted equipment solution evaluation ideas.

What should be considered when purchasing fully automatic packaging machines from China?

When purchasing fully automatic packaging machines from China, it is recommended to evaluate them from several key dimensions, including technology, supply chain, price, after-sales service, and risk control. Below is a comprehensive checklist of considerations, which can be used directly for price inquiries, supplier screening, or factory visits:   ✅ I. Clarify Required Parameters Before communicating with manufacturers, be sure to clearly define your needs; otherwise, you may be recommended unsuitable models. 1. Packaging Machine Types and Functions Pillow-type packaging machine, vertical automatic packaging machine, granulator machine, powder machine, liquid packaging machine, etc. Is automatic feeding, weighing, automatic labeling, and rejection required? 2. Packaging Materials Plastic film, aluminum foil, composite film, paper-plastic, etc. Is vacuum sealing, gas filling (modified atmosphere packaging), or heat sealing (pulse/constant temperature) required? 3. Product Characteristics Flowability (granules/powders/liquids/pastes) Is it fragile, hygroscopic, or oily? 4. Packaging Specifications Bag type (back seal/three-side seal/four-side seal/stand-up pouch) Speed ​​(bags/minute) Accuracy (± grams)   ✅ II. Points to Note When Choosing a Reliable Supplier 1. Check if they have an actual factory; avoid shell companies. Ask them to provide factory videos, live streams, or conduct an on-site factory visit. Check if the business license matches the factory address. Companies named "XX Machinery Equipment Co., Ltd." are usually more reliable than trading companies. 2. 1. Review Experience Are there similar industry case studies? Factory primarily targeting overseas markets (export-oriented factories) usually have better packaging machine stability, documentation, and export experience. 3. Inquire about core component brands These determine machine stability and lifespan. It's recommended to confirm they are original and genuine: PLC control system: Mitsubishi / Siemens / Omron Servo motor: Panasonic / Yaskawa Sensor/Photoelectric: Keyence / SICK Pneumatic components: Airtac / SMC / FESTO Vacuum pump: BUSCH (high-end) / Domestic brands are also acceptable Low-priced machines often use generic components, which significantly increases the failure rate.   ✅ III. Price Structure Transparency Packaging machine prices in China vary considerably. The main factors to consider are: 1. Does it include the following items: Automatic feeding device? Coding machine/inkjet printer? Multi-head scale? Modified atmosphere system? 1. Stainless steel type (food-grade 304SS or the cheaper 201SS?) 2. Beware of the "low price attraction + later price increase" trap. The quotation must clearly specify all configurations, brands, and warranty details.   ✅ IV. Confirm After-Sales and Technical Support Especially for exports, pay close attention to: 1. Are English user manuals, wiring diagrams, exploded views, and maintenance guides provided? 2. How long is the warranty period? How are critical components handled? Commonly mentioned: 1-year warranty on the whole machine Wearings of vulnerable parts are not covered Overseas after-sales service typically includes remote guidance and parts shipping 3. Does it support video guidance, remote debugging, and TeamViewer parameter adjustment?   ✅ V. Stability Inspection of Packaging Machine 1. If machine inspection is possible, it is recommended to check: 2. Whether the operating speed meets the standard 3. Whether bag jamming, leaks, or large errors occur after running for more than 1 hour 4. Whether the seal is firm and flat 5. Whether the film positioning and cutter position are stable 6. Whether the packaging weight maintains accuracy at high speeds 7. Whether the noise and horizontal vibration are abnormal 8. Material and wear condition of vulnerable parts   ✅ VI. Acceptance and Shipping Precautions 1. Clarify in advance: Customer sample test video 2. Request a sample of the final packaging effect 3. Whether the packaging machine has undergone durability testing 4. Whether the wooden crate export packaging meets international transportation standards   ✅ VII. International Shipping and Customs Clearance If you are located overseas, you need to confirm: Volume/Weight (choose sea, air, or rail freight) Whether CE or UL certificates are available (if required by your country) Whether the HS Code matches local customs regulations Whether the factory has export experience (important!)   ✅ VIII. Payment Method Risk Control We recommend Alibaba Escrow/Bank Letter of Credit/Phased Payment Avoid full payment upfront (especially if no factory inspection is required). Common method: 30% prepayment + 70% payment after inspection before shipment

How to buy automatic food packaging machine?

How to buy automatic food packaging machine? When purchasing an automatic food packaging machine, you must first consider the customer's packaging product situation, including the size of the food packaging bag, packaging height, and packaging speed requirements. Based on these factors, the specific model to choose is determined.   According to the main structure and configuration components of the small food packaging machine, a high-quality automatic food packaging machine must have the following basic conditions:   1. The PLC control system selected by quality, because the control system is the core control system of the whole machine, whether the goodness of the control system directly affects the stability of the machine and the service life of the machine, therefore, the control system must be able to ensure a good brand, the industry's enterprise products, such as Taiwan imported Taiwan, Japan imported Mitsubishi, imported Siemens and other brands are worth choosing.   2. The electrical components must be selected from standard low-voltage electrical manufacturing enterprises to ensure safety, reliability and durability, because the electrical control part is the brain of the packaging machine. The composition of the control line of the whole machine must ensure the convenience of maintenance and the versatility and standardization of spare parts. It is strictly forbidden to use the old series of electrical switches and other components of the old model system that have been clearly eliminated by the Ministry of Electrical and Mechanical Services (such products reduce the cost of the manufacturer, but increase the trouble for the user).   3. The steel structure of the whole machine must meet the requirements of frequent use from material to thickness, especially the structure and material use of the part in contact with the material must meet the requirements of food-grade hygiene and standard thickness and strength.   4. The appearance design of the whole machine should be reasonable, beautiful, and meet the needs of professional standardized electromechanical products, with basic safety, various prompts in key positions must be complete and obvious signs, the nameplate must indicate the number of equipment, delivery delivery date, technical parameters and implementation standards.   5. The current standard implemented by food packaging machine manufacturers is the GB/T9177-2004 standard. The distinction of machine models is mainly determined according to the width of the sealing bag of the machine. Of course, there are many non-standard models that belong to the special requirements of users. Small bag food packaging machine, automatic food packaging machine, bagged food packaging machine, food packaging machine, automatic particle packaging machine packaging machine.
