纸浆模塑有了增量利润为何不同步？下一轮看食品包装

Higher output does not mean that profit and cash flow will rise in step. Moving from egg and fruit trays into high-performance food packaging requires manufacturers to pass four gates: food-contact compliance, real-use performance, a complete bill of materials, and reliable delivery.

2026 · THREE EVIDENCE COORDINATES

These three datasets cannot be added together to produce a single industry growth rate. Together, however, they show that manufacturers expect higher output, a global company’s segment performance is improving, and a Chinese producer’s sales are growing. Whether profit and cash flow improve at the same pace remains a separate question.

Applications are also on different tracks. Chinese foodservice items are already supplied at scale; dry-molded-fiber coffee lids are in commercial production in Malaysia; Sweden is investing in equipment for fiber-based snus cans; fiber bottle caps remain under development; and an Australian fresh-meat tray is still at the concept-validation stage.

The first growth phase broadened the range of applications. The second must answer how food packaging can convert performance, compliance, and reliable delivery into profit and cash flow.

01 · APPLICATION STAGES

The first growth phase: four application stages beyond egg trays

Egg trays, fruit trays, and beverage carriers remain the volume base. Industrial cushioning, electronics inserts, and premium cosmetic packaging move the industry toward tighter requirements for structure, dimensions, surface quality, and customer approval. Meal boxes, soup bowls, fresh-food trays, puffed-food inserts, and cold-chain packaging bring food contact and real-use conditions together in a single finished article.

The first growth phase has been enabled by several processes. Conventional thick-wall or transfer-molded wet fiber serves trays, foodservice items, and cost-sensitive protective packaging. Premium wet pressing and thermoforming target thinner walls, tighter tolerances, and better surfaces. Dry Molded Fiber seeks to shorten the dewatering and drying chain associated with wet preforms. Moisture content, tooling, cycle time, energy use, precision, and yield cannot be compared across these three routes without a consistent basis.

02 · PROFIT MODELS

The post-growth reality: one industry, at least three profit models

ZX Packing Group’s audited 2025 annual report shows that revenue from foodservice items declined by 4.97%, while “other environmentally friendly packaging,” driven by sales of new premium industrial-packaging products, grew by 64.14%. The latter generated only RMB 16.799 million in annual revenue, compared with RMB 1.442 billion from foodservice items.

In the same year, the company’s output of foodservice items and other products declined by 19.76%, while sales volume fell by 1.40%. Domestic sales rose by 8.21%, but export sales declined by 4.62%. The annual report primarily associates the production decline with U.S. trade measures and the ramp-up of capacity in Thailand.

Nominal capacity is not stable output, an equipment order is not a customer order, and an exhibition sample is not a repeat purchase. Application expansion answers whether there is work to be done; unit cost per conforming product and cash collection answer whether value is being created.

03 · THE SECOND GROWTH PHASE

Why food packaging is harder—and more valuable—in the second growth phase

Precision electronics inserts and premium cosmetic packaging can also create high value. Food packaging warrants separate discussion because it combines high frequency, broad volume, and complex service conditions, testing materials, structures, regulation, manufacturing, and end-of-life performance at the same time.

Meal boxes, soup bowls, fresh-food trays, frozen and reheated foods, prepared foods, and supermarket ready-to-eat packaging are not purchased merely for “high plant-fiber content.” Customers buy defined outcomes: no leakage with hot soup, no migration of oils and fats, no loss of stiffness under condensation, no premature edge failure, and no lid disengagement.

China’s Environmental Code, effective from 15 August 2026, requires packaging to be reasonable and reduced and incorporates green procurement and green supply chains into corporate responsibilities. Beijing’s Guidelines for the Use of Green Packaging by Food-Delivery Merchants, effective from 1 September 2026, translate food temperature, package dimensions, layer count, sealing, and readily separable structures into merchant actions.

Laws and recommended local standards have different legal force, and neither specifies molded fiber, waterborne coatings, PHA, or PLA. Instead, they change the procurement questions: Has the structure been reduced? Is the bill of materials traceable? Does the product pass its intended food-use conditions? Are the food-contact safety, repulpability, compostability, and claimed post-use pathway credible? Can the plastic content be calculated to determine whether the product falls within the scope of the Single-Use Plastics Directive (SUPD)?

04 · BILL OF MATERIALS AND COATING

The key to better quality: a complete bill of materials and the functional coating

Wood pulp, recovered pulp, bamboo pulp, bagasse pulp, and straw pulp answer the question, “Where does the fiber come from?” Bamboo pulp is already within the raw-material boundary for molded fiber, but it does not automatically prove that the finished article is food-contact compliant, recyclable, compostable, or low carbon.

High-performance molded fiber necessarily involves formulations and additives as well as barrier coatings; bio-based materials are part of this higher-value market. Professional assessment must determine whether each component is necessary, traceable, suitable for the target food and temperature, stable across batches, and compatible with the declared end-of-life pathway.

“Waterborne” describes only the dispersion or application medium. After the water evaporates, the film-forming polymer, formulation, coat weight, and film continuity determine grease resistance, water resistance, resistance to hot liquids, heat sealability, regulatory classification, and end-of-life behavior.

PE lamination |Mature performance, heat sealing, and supply chains; paper–plastic separation, repulping, and non-compostable end-of-life routes still require management.

Waterborne or dispersion systems such as EAA, acrylics, and PU |Flexible formulations and relatively mature production experience; being “waterborne” does not change the identity of the film-forming polymer.

Natural polymers, wax/resin systems, and mineral combinations |Can provide part of the barrier function, but humidity, thermal stability, cracking on flexing, and the bonding phase remain constraints.

PHA waterborne barrier route |Places food-barrier development and a verified biological-treatment pathway on the same engineering route. Evidence must still be established for the specific material, thickness, formulation, and finished-article scope.

05 · BIOTEN MATERIAL INTERFACES

BIOTEN Observer: three material interfaces, each addressing a different failure mode

The following observations concern material-development interfaces associated with BIOTEN Packaging; they are not three product cards.

PHA waterborne barrier coating for the food-contact surface |Designed for hot soup, oils and fats, sauces, fresh-food condensation, and freeze–reheat conditions. DIN CERTCO and BPI list records for Bioten™ PHA Barrier Coating materials, components, or coatings. These records do not prescribe a coat weight and do not replace certification of the finished food container. Procurement must still establish the minimum effective dry coat weight, edge continuity, drying window, and target food conditions within the same SKU.

Fiber-performance copolymer |Acts within the pulp, wet preform, and fiber network to improve strength, forming stability, lightweighting, and fiber-use efficiency. It may also be applied by surface spraying; addition rates of only a few parts per thousand in the furnish can provide broad reinforcement or enable weight reduction.

PHA waterborne overprint varnish for the exterior surface |Intended for premium wet-pressed, cosmetic, electronics, or high-end foodservice applications requiring appearance, tactile quality, abrasion resistance, and surface protection. It is commercially meaningful only when the brand experience can support the added process cost. Washable reuse remains a development direction within the BIOTEN Developer molded-fiber system.

The three interfaces act respectively within the fiber network, on the food-contact inner surface, and on the brand-facing outer surface. Their common threshold is not the material name, but a precisely defined SKU, a complete finished article, repeatable data, and unit cost per conforming product.

06 · RELIABLE DELIVERY

Converting profit potential into cash: from minimum effective coat weight to cash collection

Commercial validation only begins after the coating route is selected. A high-performance molded-fiber food container must, at minimum, lock down the fiber and additive formulation, coating SKU, application method, wet and dry coat weights, drying window, edge coverage, contents, temperature, sealing, stacking, and distribution conditions.

There is currently no publicly available minimum BIOTEN spray application or dry coat weight that applies across SKUs. It must be determined through design of experiments (DOE): under the same article, service conditions, and acceptance criteria, compare coat weight, drying, barrier performance, yield, and cost to identify the minimum effective operating window.

Pulp suppliers must deliver fiber consistency. Material suppliers must deliver formulation identity, application windows, and end-of-life evidence. Equipment and tooling suppliers must integrate coating, drying, and in-line inspection into the production line. Finished-article manufacturers must place yield, certification, customer complaints, cost, and cash collection on the same operating dashboard.

The real breakthrough worth expecting is not more samples, but precisely defined SKUs that conform across batches, win repeat orders, and convert profit into cash.

The second growth phase is not another fiber story

The first growth phase has already taken molded fiber into industrial inserts, electronics, cosmetics, fresh foods, and complex components. The second must make food packaging withstand simultaneous tests of food contact, real-use performance, regulatory classification, end-of-life pathways, and mass-production economics.

Incremental volume comes from more applications. Better quality comes from a complete bill of materials, functional layers, and an evidence package. Value creation can be realized only through yield, unit cost per conforming product, customer approval, repeat purchases, complaint performance, and cash collection.
