Chengda's New Straight Tube Machine: Substitution Advantages and Application Value in Disposable Paper PackagingIn the field of disposable paper packaging production, the iteration of equipment directly affects cost control, environmental protection attributes, and product adaptability. Chengda's new straight tube machine, with its precise adaptation to "lightweight paper packaging", has become an ideal alternative to the original spiral tube paper tube machine. It demonstrates significant advantages especially in food packaging and daily disposable paper container scenarios. The following analysis is carried out from three dimensions: substitution logic, core application scenarios, and core values.   I. Substitution Logic: Why is the New Straight Tube Machine Suitable for Lightweight Paper Packaging? The original spiral tube paper tube machine is designed to focus more on the production of "high-strength, thick-material" paper tubes (such as industrial load-bearing paper tubes and thick-walled storage tubes). Although its spiral winding process can improve structural stability, it has the problems of "process redundancy and high cost" when producing **thin-material, lightweight, and disposable** paper packaging.   In contrast, Chengda's new straight tube machine has been optimized specifically for the characteristics of lightweight paper products:   - Simplified process: It eliminates the complex multi-layer spiral winding steps of the spiral tube machine and adopts a straight tube forming process that is more suitable for thin paper (such as 200-350g/m² thin kraft paper and food-grade white cardboard), reducing paper waste and processing time.   - Material adaptability: It supports the precise forming of food-grade thin paper, avoiding the "excessively thick packaging and redundant weight" caused by the thick-walled process, and is more in line with the needs of "lightweight and low material consumption" for disposable products.   - Cost adaptability: The simplified process directly reduces equipment energy consumption and production working hours. At the same time, it reduces the rejection rate caused by "wrinkling and breaking" which are prone to occur when thin paper is used in spiral winding, thereby lowering production costs from three aspects: "equipment + consumables + efficiency".   II. Core Application Scenarios: Accurately Matching the Needs of Disposable Paper Packaging The substitution value of Chengda's new straight tube machine is concentrated in its adaptation to "lightweight, disposable, food-grade/daily-use" paper packaging. The typical scenarios can be divided into two categories: 1. Disposable Food Packaging To meet the core needs of "hygiene, portability, and low cost" for food packaging, the paper tubes produced by the new straight tube machine can directly replace traditional small plastic/metal packaging. Specific applications include:   - Tea packaging: Producing small straight tube paper cans with a diameter of 3-5 cm and a height of 8-12 cm. The inner wall can be covered with a food-grade PE film to prevent moisture. Each can can hold 5-10 grams of loose tea or tea bags. Compared with traditional iron cans/aluminum cans, the cost is reduced by 30%-50%, and the cans can be naturally degraded after being discarded.   - Potato chip/snack packaging: Adapting to the demand for "small-portion disposable packaging", it produces paper tubes with a diameter of 5-8 cm and a height of 10-15 cm, which are equipped with an easy-tear lid design. It replaces some plastic snack cans, reduces plastic usage, and the buffering property of the paper tubes can reduce the breakage rate of potato chips.   - Other food scenarios: Such as small candy cans and trial-pack paper tubes for nuts. All of these can be quickly formed by the equipment and comply with the safety standards for food contact materials (e.g., GB 4806.8-2016).  2. Daily Disposable Paper Containers For daily scenarios requiring "disposal after use and low service strength", the paper tubes produced by the new straight tube machine do not need to pursue high strength, but focus more on "low cost and easy degradation". Typical applications include:   - Toothpick tubes/cotton swab tubes: Producing mini straight tubes with a diameter of 2-3 cm and a height of 6-8 cm. The inner wall does not require complex treatment, and the cost per tube can be controlled at a few cents. It replaces traditional plastic toothpick tubes and is more acceptable in catering scenarios.   - Disposable ashtrays: Producing short straight tubes with a diameter of 8-10 cm and a height of 3-5 cm. The bottom can be treated for leak prevention (e.g., covered with a thin wax layer), which is suitable for scenarios such as restaurants and hotels that require "disposable use and centralized recycling". Compared with plastic ashtrays, it is more environmentally friendly and causes no plastic pollution after disposal.   III. Core Values: Dual Breakthroughs in Cost Reduction and Environmental Protection The substitution significance of Chengda's new straight tube machine essentially lies in achieving a "win-win" situation of "cost reduction and environmental protection" through "equipment adaptation to scenarios":    1. Significantly Reducing Packaging Costs - Consumable cost: The paper consumption of lightweight paper packaging is only 1/3 to 1/2 of that of traditional spiral tube paper tubes, and the purchase unit price of thin paper is lower.   - Production efficiency: The production speed of the straight tube forming process is 20%-30% faster than that of spiral winding, resulting in higher output per unit time and lower equipment depreciation and labor costs after allocation.   - Downstream adaptation: Downstream customers of disposable packaging (such as tea shops, snack manufacturers, and catering enterprises) are highly sensitive to costs. The packaging produced by the new straight tube machine can help customers reduce the pricing of end products and enhance market competitiveness.  2. Strengthening Environmental Protection Attributes and Conforming to Policy Trends - Material environmental protection: Paper packaging can be 100% degraded (if not covered with non-degradable film), or achieve full-life-cycle environmental protection through a combination of "paper + degradable film", avoiding the "white pollution" problem of plastic packaging.   - Policy adaptation: Currently, domestic and foreign policies on "plastic ban and restriction" for food packaging and disposable products are continuously tightened (e.g., China's *Opinions on Further Strengthening the Governance of Plastic Pollution*). Paper packaging has become the first choice for compliance. The application of the new straight tube machine can help enterprises lay out environmentally friendly packaging in advance and avoid policy risks.   - Brand value: For enterprises that focus on the "green brand image" (such as high-end tea brands and healthy snack brands), the use of paper packaging can convey the concept of environmental protection and enhance consumers' favorability. In conclusion, Chengda's new straight tube machine is not a simple "equipment replacement", but a "precision upgrade" for the scenario of "lightweight disposable paper packaging". It not only solves the "cost redundancy" problem of the original spiral tube paper tube machine in this scenario but also conforms to the core needs of the current packaging industry for "cost reduction and environmental protection". It is especially suitable for production enterprises that take "small-batch, multi-category" disposable paper packaging as their core products.
