The base and lid form one piece, so staff do not need to store or match separate lids. This format is designed for full takeaway portions such as rice dishes, pasta, sandwiches, burgers, salads, chicken, and combination meals.<\/p>\n<p>The model is part of Manluen\u2019s wider range of <a href=\"https:\/\/www.manluenpack.com\/ja\/product-category\/clamshell-containers\/\">clamshell containers<\/a>.

Staff can fill, close, label, and stack an order without searching for a separate lid. This can be useful for restaurants, takeout counters, caterers, food trucks, and commissary kitchens.<\/p>\n<p>The design also saves space when nested. However, buyers should test how easily containers separate from the stack. Excessive nesting force can slow packing, while a weak hinge or closure can create failures during delivery.<\/p>\n<p>Check these points with samples:<\/p>\n<ul>\n<li>How quickly staff can separate and close each container<\/li>\n<li>Whether the hinge stays aligned after refrigeration or heating<\/li>\n<li>Whether the closure remains engaged during transport<\/li>\n<li>Whether the opening tab is easy for customers to use<\/li>\n<li>Whether labels or tamper seals adhere to the surface<\/li>\n<\/ul>\n<p>Manluen\u2019s guide to <a href=\"https:\/\/www.manluenpack.com\/ja\/news-en\/what-is-clamshell-packaging\/\">what clamshell packaging is<\/a> explains the difference between hinged packages, separate-lid containers, and other clamshell materials.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-3257\" src=\"https:\/\/www.manluenpack.com\/wp-content\/uploads\/2025\/04\/WL-P91-manluen-clamshell-takeout-plastic-containers-scaled.webp\" alt=\"Wl P91 Manluen Clamshell Takeout Plastic Containers\" width=\"2560\" height=\"1707\" title=\"\"><\/p>\n<h2>PP Material and Food-Contact Use<\/h2>\n<p>&nbsp;<\/p>\n<p>WL-P91 uses polypropylene. PP is commonly selected for prepared-food containers because it combines low weight, toughness, and useful heat performance. These general properties do not make every PP container suitable for every food or temperature.<\/p>\n<p>In the United States, 21 CFR 177.1520 covers specified olefin polymers, including polypropylene, for food-contact use subject to its provisions. A finished container also includes pigments, fillers, processing aids, and other components that must suit the intended use.<\/p>\n<p>Buyers should request product-specific evidence rather than rely on the phrase \u201cFDA approved.\u201d The guide to <a href=\"https:\/\/www.manluenpack.com\/ja\/news-en\/what-is-food-grade-packaging\/\">food-grade packaging<\/a> explains why the regulatory status of a resin is not the same as universal approval of a finished container.<\/p>\n<p>The broader <a href=\"https:\/\/www.manluenpack.com\/ja\/news-en\/food-packaging-materials\/\">food packaging materials guide<\/a> compares PP with PET, PS, OPS, paper, bagasse, aluminum, and glass.<\/p>\n<p>&nbsp;<\/p>\n<h2>Is WL-P91 Microwave-Safe?<\/h2>\n<p>&nbsp;<\/p>\n<p>The current product description identifies WL-P91 as a <a href=\"https:\/\/www.manluenpack.com\/ja\/news\/can-you-microwave-food-in-a-plastic-container\/\">microwaveable PP food box.<\/a> Buyers should still request the latest instructions for the exact color and production version before use.<\/p>\n<p>Microwave performance depends on the resin grade, additives, wall thickness, food, fill weight, starting temperature, heating time, and power level. A material melting point is not a consumer heating limit. Do not convert a polymer melting point into a blanket claim such as \u201csafe to 110\u00b0C\u201d or \u201csafe for repeated heating.\u201d<\/p>\n<p>Use the container only under the supplier\u2019s stated conditions:<\/p>\n<ol>\n<li>Confirm that the exact SKU is labeled for microwave use.<\/li>\n<li>Check whether the lid must be opened, vented, or left unlatched.<\/li>\n<li>Use the stated time and power level.<\/li>\n<li>Avoid heating an empty container.<\/li>\n<li>Do not use the box in an oven, under a grill, or over an open flame.<\/li>\n<li>Discard a container that is cracked, warped, or otherwise damaged.<\/li>\n<\/ol>\n<p>The <a href=\"https:\/\/www.manluenpack.com\/ja\/news\/plastic-food-packaging-compliance-2026\/\">plastic food packaging compliance guide<\/a> provides more detail on matching materials to intended use and destination-market requirements.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-3258\" src=\"https:\/\/www.manluenpack.com\/wp-content\/uploads\/2025\/04\/WL-P91-manluen-to-go-plastic-clamshell-containers-scaled.webp\" alt=\"Wl P91 Manluen To Go Plastic Clamshell Containers\" width=\"2560\" height=\"1707\" title=\"\"><\/p>\n<h2>What Foods Work Well in WL-P91?<\/h2>\n<p>&nbsp;<\/p>\n<p>The large one-compartment format suits meals that benefit from an open base area.

Test it with the heaviest, hottest, oiliest, and most moisture-rich foods in the intended menu.<\/p>\n<ol>\n<li>Fill the container to the planned portion weight.<\/li>\n<li>Close it using the normal staff process.<\/li>\n<li>Hold it for the full expected waiting and delivery time.<\/li>\n<li>Tilt and carry it in the actual delivery bag or carton.<\/li>\n<li>Stack it at the expected height and inspect the bottom package.<\/li>\n<li>Check the hinge, rim, corners, base deflection, closure, and food movement.<\/li>\n<li>Repeat after refrigeration or microwave heating when those uses apply.<\/li>\n<\/ol>\n<p>This test shows whether the container works with the real food. It is more useful than broad claims about \u201cunbeatable durability\u201d or a \u201cprecision-engineered seal.\u201d<\/p>\n<p>&nbsp;<\/p>\n<h2>Ventilation, Crispness, and Condensation<\/h2>\n<p>&nbsp;<\/p>\n<p>Hot fried food releases steam. A fully closed box can trap that moisture and soften the surface of fries, chicken, or baked food. Venting can help, but it may also reduce heat retention or allow sauce to escape when the box tilts.<\/p>\n<p>If ventilation is required, ask whether the chosen WL-P91 version supports a vented configuration. Test the vent size and position with the actual menu. Do not assume that a custom feature is standard on every unit.<\/p>\n<p>For chilled food, inspect condensation after refrigeration and display. PP is not fully transparent, so the package is usually selected for handling and heat performance rather than crystal-clear product display.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-4561\" src=\"https:\/\/www.manluenpack.com\/wp-content\/uploads\/2025\/12\/WL-2501c-manluen-blueberry-clamshell-containers.webp\" alt=\"Wl 2501c Manluen Blueberry Clamshell Containers\" width=\"1080\" height=\"1520\" title=\"\"><\/p>\n<h2>Stacking, Storage, and Delivery<\/h2>\n<p>&nbsp;<\/p>\n<p>The 230\u00d7230 mm footprint requires more shelf and bag space than smaller clamshells. Measure the packing station, storage rack, delivery bag, and shipping carton before approval.<\/p>\n<p>The current product specification lists 150 pieces per carton and a carton size of 460\u00d7285\u00d7470 mm. Use those figures to estimate storage and freight needs, then confirm them on the final purchase specification.<\/p>\n<p>During a stack test, check whether the lid contacts the food and whether the bottom container deforms. Weight, food temperature, stacking height, and travel time can all change the result.<\/p>\n<p>&nbsp;<\/p>\n<h2>Customization and Branding<\/h2>\n<p>&nbsp;<\/p>\n<p>Color, labels, sleeves, and printing can help a restaurant identify orders or present its brand. Customization may also change lead time, MOQ, cost, and product performance.<\/p>\n<p>Before approving a custom order, confirm:<\/p>\n<ul>\n<li>The color specification and permitted tolerance<\/li>\n<li>The printable or label area<\/li>\n<li>Ink, adhesive, and label suitability for the food temperature<\/li>\n<li>Whether customization changes food-contact documentation<\/li>\n<li>Whether the hinge and closure still perform after production changes<\/li>\n<\/ul>\n<p>A snap closure is not automatically tamper-evident. If the business needs visible evidence of opening, add a compatible seal or select a purpose-designed feature. The guide to <a href=\"https:\/\/www.manluenpack.com\/ja\/news-en\/what-is-tamper-evident-packaging\/\">tamper-evident packaging<\/a> explains this distinction.<\/p>\n<p>&nbsp;<\/p>\n<h2>Recycling and Environmental Claims<\/h2>\n<p>PP is a recyclable resin, but local collection and processing determine whether a used WL-P91 is actually recycled. Food residue, labels, pigments, sorting equipment, and local end markets all affect acceptance.<\/p>\n<p>Do not state that the container can be recycled in most municipal programs without evidence for the target market. Avoid broad \u201ceco-friendly\u201d claims. Give customers local disposal instructions where possible.<\/p>\n<p>Compostable liners do not make a PP container compostable. Mixed-material additions can also make separation harder. Buyers comparing alternatives should consider food protection, material use, collection infrastructure, and the risk of food waste.
