Question: What do the recycling numbers on plastic takeout containers actually tell a restaurant buyer? Answer: The number identifies a plastic resin. It does not establish that the finished container can go in a customer's recycling bin, that a local facility can sort its shape, or that it is safe for hot food or microwave reheating. For a useful disposal instruction, verify the exact item, the collection program, and how clean the container must be.
That distinction becomes practical when a café changes its salad bowl, a caterer chooses a hot entrée container, or a multi-location restaurant tries to print one disposal message on every bag. A number is a material clue. The decision is made by the whole package and the place it is discarded.

Start with the resin, then stop reading more into the number
A resin identification code is the small number in a triangle molded into many plastic items. The U.S. National Institutes of Health identifies #1 as PET (polyethylene terephthalate) and #5 as PP (polypropylene). PET is often used in clear food packaging; PP appears in some takeout containers. The code identifies the base plastic family, not the collection system that will process a particular bowl or clamshell. See the NIH resin-code list.
Three further questions remain unanswered by the mark: Can this exact item serve the food as packed? Does the local recycler accept its shape and components? Is it empty enough to enter that stream? The U.S. Environmental Protection Agency says resin symbols identify plastic type but do not necessarily mean an item is collected locally. It also says food debris must be removed before an accepted container is recycled. Read EPA's plastic-container guidance.
The same package can get different answers in different cities
New York City says its residential program accepts most rigid plastic food containers and clamshells regardless of the resin number. Portland, Oregon, instead tells households and workplaces to ignore the numbers and put only bottles, jugs, buckets and tubs at least 2 by 2 inches in its recycling container. A clamshell cannot be added to Portland's list merely because its plastic is #1 or #5. Check NYC's rigid-plastic rules and Portland's shape-based rules.
Those examples illustrate a general point, not a promise for either product in this article. A restaurant's commercial hauler, an event venue, and a customer's home program may have different instructions even in one city. Ask the program that will actually receive the used item. If the answer is unclear, avoid putting a blanket “recycle me” message on a package.
Buy for the food first; write the disposal instruction second
For chilled, visible food, EcoQuality's clear PET salad bowls with matching lids offer a way to show salads, fruit or cold prepared foods. The live listing offers multiple capacities and pack quantities. It describes the material as PET and calls it “100% recyclable”; that is a company claim, not evidence that every local program takes this exact bowl and lid. Check the selected size, filled-food clearance, lid closure, local rules and current pack before ordering.

For hot entrée service, EcoQuality's 38-ounce black PP hinged takeout container with a clear lid is a different format. EcoQuality lists the container as polypropylene and says it is microwave safe. Treat that as the listing's product claim; ask for directions for the complete hinged package before telling customers to reheat with the lid closed. A clear lid's appearance does not prove it uses the same resin as the base. The black color also does not, by itself, answer whether a particular recycler accepts it.

The buying comparison is therefore operational: a transparent bowl helps a cold display; a hinged entrée pack avoids tracking a loose lid and is listed for reheating. Neither resin name substitutes for a filled-order test. Before a larger purchase, close a normal portion, carry it along the actual handoff route, stack it as staff will, and check for condensation, lid lift, leaks and presentation. This is a recommended test protocol, not a claim that EcoQuality has run or passed a laboratory test on these items.
The five-field disposal card
Use one small card per packaging SKU. Keep it with the purchasing record so a location manager can update the customer instruction when a product or hauler changes. This is our editorial decision tool, built from the cited material and city guidance.
| Field | What to record | Why it matters |
|---|---|---|
| 1. Exact item | Product URL, selected size/pack, and a photo | A changed SKU may have a different material or shape. |
| 2. Components | Base, lid, liner and label separately; resin if documented | Do not assume a clear lid matches its base. |
| 3. Destination | Restaurant hauler, event venue or customer locality | “Locally accepted” depends on where it is discarded. |
| 4. Accepted form | Ask about bowls, tubs and clamshells, not only #1 or #5 | Sorting rules often depend on shape and size. |
| 5. Condition | Record “empty,” scrape/rinse instruction and review date | Food residue can disqualify an otherwise accepted item. |
Worked example: Suppose a restaurant uses a rigid PP clamshell and customers discard it in two cities. A resin-only label would give both customers the same answer. The five-field card instead sends staff to each official program: NYC lists rigid takeout clamshells among accepted plastics, while Portland limits collection to specified bottle, jug, bucket and tub forms. The operator still confirms whether its exact item and commercial or residential route fit those instructions, then writes a short location-specific message. No recycling rate is inferred from either city list.
For a multi-location operation, keep the field values in a shared sheet with the source URL and last-check date. The time spent checking a new SKU is a purchasing cost, but it also prevents one national label from contradicting a local bin sign. Compare the price of a usable complete set—container, included or separate lid, storage space, and expected replacement or spill risk—rather than judging by case price or resin alone. Record your own service results; do not substitute a supplier's marketing language for a route trial.
What this means for your business
Choose the container that protects the actual meal, then document how each location should handle it after use. For a cold menu, compare the available clear PET bowl sizes. For a hot entrée, review the black PP hinged container's current packs and request component-specific reheating directions when needed. Test filled samples and ask the receiving recycler about the exact form before printing disposal copy. If purchasing across several menus or locations, contact EcoQuality about wholesale quantities with your menu, pack count and destination list.
Frequently asked questions
Does #1 or #5 mean a takeout container is recyclable?
No. #1 identifies PET and #5 identifies PP; neither mark says a particular program collects that shape. Ask the local program about the exact bowl, tub or clamshell and its food-residue rule.
Does #5 make a container microwave safe?
No. Resin type is not a use instruction. Check the exact manufacturer's directions for the base and lid. The EcoQuality PP container discussed above is listed as microwave safe, but the listing does not resolve every lid-use detail; do not generalize its claim to other PP packages.
Can a clear compostable plastic lid join PET recycling?
Do not infer that a clear lid is PET. EPA says compostable plastics are not intended for conventional plastic recycling and can disrupt that stream. Identify the actual material and follow the receiving program's rules. See our separate compostables acceptance guide if that is the product you are buying.
How clean is clean enough?
First confirm the item is accepted. EPA says to scrape or rinse food residue and describes “spatula-clean” as sufficient for an accepted plastic container. Follow any stricter instruction from your specific collection program.
