はじめに

The WL-P61 is a compact black PP clamshell container for burgers, sandwiches, salads, fruit and small takeaway meals. Its lid and base are joined by one hinge, so food-service staff can fill and close the container without matching two separate pieces.

Buyers can view the WL-P61 6×6-inch black clamshell container or compare it with other clamshell containers. Because the product uses PP, our guides to food packaging materials および microwaving food in plastic containers provide useful background.

This guide focuses on the current WL-P61 specification, practical food-service uses and the checks a wholesale buyer should complete before ordering.

Current WL-P61 Specifications

The live product page identifies the WL-P61 Black as a PP hinged clamshell. The main comparison table gives a nominal product size of 150 × 150 × 70 mm. A second specification table on the same page lists 152 × 152 × 76 mm. Buyers should therefore request the current technical drawing and approved sample before treating either measurement as final.

アイテム	Current listed specification
モデル	WL-P61 Black
Structure	One-piece hinged clamshell
素材	PP
Nominal product size	150 × 150 × 70 mm
Pack quantity	250 pieces per carton
カートンサイズ	470 × 310 × 320 mm

The current product page does not publish a verified volume in millilitres. Buyers who control portions by volume should test the finished meal or request the approved capacity from Manluen.

How the Hinged Square Design Works

The WL-P61 combines the lid and base in one formed piece. This reduces the chance of staff selecting the wrong lid during service. The square footprint also uses shelf and carton space differently from a round container.

The design is useful when the food fits inside the base without pressing against the lid. A burger, sandwich, salad or snack can work well, but tall buns, bulky garnishes and overfilled meals may prevent the closure from engaging correctly.

For a broader explanation of formats and applications, see Manluen’s guide to what clamshell packaging is.

What to Test

• Usable internal length, width and height
• Clearance above the finished food
• Hinge movement after filling and closing
• Closure engagement around the full edge
• Base flex under the heaviest planned meal
• Stacking stability inside the delivery carton or bag

PP and Microwave Use

The current WL-P61 product page describes the container as microwaveable and identifies the material as PP. That does not mean every PP package can be heated under any time or temperature. Food composition, heating time, portion size and container geometry all affect the temperature reached during microwaving.

FDA treats refrigerated storage, reheating in the container and high-temperature cooking as different conditions of use. USDA food-safety guidance also advises consumers to use plastic cookware that is specifically manufactured and labeled for microwave use.

For the WL-P61, buyers should request the product-specific heating instructions and the supporting food-contact documentation. Those instructions should state:

• Whether the container should be vented or partially opened
• The permitted microwave time and power
• The maximum intended food temperature
• Any restrictions for oily, sugary or high-fat foods
• Whether the product is intended for one heating cycle or repeated use

Do not substitute a general “PP is microwave-safe” statement for instructions tied to the finished WL-P61 configuration.

What to Verify About “Mineral Clamshell” Claims

The article’s original positioning refers to a mineral clamshell. The current WL-P61 product page, however, lists the material simply as PP and does not publish a mineral type, filler percentage or supporting environmental data.

If a quotation describes the product as mineral-filled PP, ask for the formulation declaration that can be shared with customers. Mineral filler can change stiffness, weight, impact performance and processing, but it does not automatically prove that a package uses less energy, has a lower carbon footprint or will be accepted by local recyclers.

A buyer should request:

• The mineral type and percentage range
• The total PP content and any other additives
• Mechanical test results for the finished container
• Migration or food-contact evidence for the stated conditions of use
• Any life-cycle or carbon claim methodology used in marketing
• Written guidance on disposal and local recycling limitations

Do not describe mineral-filled PP as biodegradable or compostable. Buyers seeking a fiber-based alternative can compare the format with bagasse and biodegradable clamshell packaging, while checking the required certification and local composting infrastructure.

Suitable Food-Service Uses

Burgers and Sandwiches

The 6×6-inch format suits compact burgers and sandwiches when the finished height remains below the lid. Test tall buns, skewers and layered fillings because they can distort the top or stop the container from closing.

Salads and Fruit

The wide base provides room for small salads, cut fruit and cold sides. Dressings, syrups and sauces should go in a separate closed cup unless a filled-sample test confirms the package can contain them during the planned journey.

Prepared Meals and Takeaway

The black base can frame rice dishes, pasta, fried foods and other small prepared meals. Hot food may create steam and condensation, so the packing procedure should match the closure and venting instructions supplied for the product.

Meal Prep and Grab-and-Go

The connected lid can simplify rapid packing. For operations that need separate lids, deeper portions or different capacities, compare the WL-P61 with Manluen’s food storage containers.

Closure Performance Is Not the Same as Leakproofing

A hinged closure can help keep solid food inside the package, but the word “leakproof” should be supported by a test method and acceptance standard. A container that works for a sandwich may not hold soup, curry or a thin sauce when tilted.

Run a filled-package test before using the WL-P61 for wet food:

1. Fill the container with the intended food at the normal packing temperature.
2. Close every point around the edge.
3. Hold the package level for the expected storage time.
4. Tilt it through the angles likely during bagging and delivery.
5. Place it in the actual delivery bag or carton.
6. Inspect the closure, hinge, base and surrounding packaging.

If liquid escapes, use a separate sauce cup or select a container designed and tested for liquid food.

Food-Contact Compliance

Compliance is tied to the finished article, its components and the intended conditions of use. FDA explains that a food-contact substance that is a food additive must be authorized for that use before it is marketed in the United States. FDA also evaluates migration according to the intended food type, contact time and temperature.

For the EU, Regulation (EU) No 10/2011 establishes rules for plastic food-contact materials, including migration limits and declaration-of-compliance requirements. A generic resin name or a broad statement such as “FDA approved” does not replace the documents for the finished product.

Buyers can review Manluen’s plastic food packaging compliance guide and its explanation of which agencies regulate food packaging. General company documents are available on the 認証ページ, but buyers should still request evidence tied to the WL-P61 and target market.

Documents to Request

• The current technical drawing and approved dimensions
• The material declaration for the finished base and lid
• The relevant U.S. or EU food-contact compliance statement
• Migration-test conditions covering the intended food, time and temperature
• Product-specific microwave instructions and restrictions
• A current production sample from the quoted configuration

Recycling and Environmental Claims

PP is often identified by resin code 5, but the code does not guarantee that a local collection program accepts the finished container. Food residue, labels, pigments, fillers and local sorting equipment can affect recovery.

Use precise language. “Made from PP” is a material statement. “Recyclable,” “lower carbon” and “uses less plastic” are separate claims that require evidence and must reflect the market where the product is sold.

For used food containers, tell customers to follow local collection rules. Do not promise curbside acceptance across every city or country.

Wholesale Buying Checklist

A complete request for quotation should cover the product and its intended use:

• WL-P61 model, color and approved drawing
• Food type, portion size and packing temperature
• Refrigerated, room-temperature or microwave use
• Required closure and leak-test performance
• Quantity, case pack, pallet plan and delivery schedule
• Target country and required compliance documents
• Custom color, embossing, label or outer-carton requirements
• Whether a mineral-filled formulation is being requested or quoted

MOQ and lead time can change with stock, color, printing and production configuration. Review Manluen’s manufacturing background, then request a current sample and quotation with the intended use.

よくある質問

What is the WL-P61 made from?

The current product page lists the WL-P61 Black as PP. If a quotation uses the term “mineral clamshell,” request the full material declaration and mineral-filler information for that configuration.

What is the WL-P61 size?

The main product table gives 150 × 150 × 70 mm, while a secondary specification table gives 152 × 152 × 76 mm. Request the current approved drawing before designing labels, cartons or automated packing equipment around the dimensions.

Is the WL-P61 microwave-safe?

The current product page describes it as microwaveable. Use it only according to the product-specific time, power, venting and food restrictions supplied for the quoted SKU. Do not apply a general 120°C claim without the corresponding test report or instructions.

Is the WL-P61 leakproof?

The product has a hinged closure, but the current page does not publish a defined leak-test result. Test the finished food and delivery route before using it for sauces, broth or other liquids.

Can the WL-P61 be frozen?

Do not assume freezer suitability from the PP material alone. Ask whether the finished container has been tested for the required freezing temperature, duration, impact and thawing method.

What is the minimum order quantity?

The current MOQ depends on stock, color, customization and production scheduling. Request the commercial terms for the exact WL-P61 configuration.

結論

The WL-P61 is a compact hinged PP clamshell for small prepared meals, sandwiches, burgers, salads and fruit. Its one-piece design can simplify packing, but buyers should verify the current dimensions, closure performance, microwave instructions and food-contact documents before ordering. Claims about mineral filler, leak resistance, freezing, recyclability or carbon reduction should be supported separately.
