A cold-drink lid does three jobs at once: it keeps the drink in, it lets the customer see it, and it has to work with the cups, straws and dispensing habits already in your shop.
It is written for cafe owners, juice and smoothie bars, bubble tea shops, food truck operators and packaging buyers who need a clear dome lid for cold drinks. If you serve hot drinks, read the temperature section before anything else.
| Item No. | Product Name | Weight | Pcs/Sleeve | Qty/Ctn |
|---|---|---|---|---|
| GK98/LD | 98 Dome Lid | 3.8 g | 100 pcs x 10 | 1000 pcs |
Source: manufacturer product page. The "98" refers to the nominal cup caliber in millimeters, which is the number to match against your cup rims.
| Figure | Calculation | Why it matters |
|---|---|---|
| About 380 g per sleeve | 3.8 g x 100 lids | Lets you check that a delivery matches the order by weight. |
| About 3.8 kg net lid weight per carton | 3.8 g x 1000 lids | Useful for freight estimates. Carton packaging adds to this, so ask for the gross weight. |
| 1000 lids per carton | 10 sleeves x 100 | Sleeves of 100 are easy to count at opening and closing, and easy to load into a lid dispenser. |
Clear PET. The manufacturer describes the lid as crystal clear, food-grade PET that resists cracking. Clarity matters most for layered drinks, since customers judge what they are buying by looking at it.
Arched dome. The raised profile gives headroom above the rim for whipped cream, fruit pieces or milk foam, so the topping does not press against the lid. It also leaves room for a slightly fuller pour than a flat lid allows.
Integrated straw hole. The hole is sized for standard straws. A close-fitting hole limits splashing and keeps the straw from drifting while the cup is carried.
"Multifit" design. The page says the lid suits multiple cup sizes. The only caliber stated in the item data is 98 mm, so treat "multifit" as meaning several cup heights and capacities that share a 98 mm rim, and confirm the exact cups with the supplier.
The same manufacturer sells flat, dome and straw-free lids in several diameters. Each fits a different service pattern.
| Lid style | Best for | Trade-off | Example from this supplier |
|---|---|---|---|
| Dome with straw hole | Smoothies, milkshakes, iced coffee with toppings | Takes more shelf and carton space than flat lids | GK98/LD, GK90/LD |
| Flat lid | Portion cups, stacking, compact storage | No headroom for toppings | GK78/LF, GK90/LF |
| Straw-free lid | Programs that want to cut straw use | Not suited to thick blended drinks | GK90/LS, GK92/LS |
You can browse the full range in the PET lid category, and find matching cups under PET cups. For a similar dome in a smaller diameter, see the GK78/LD beverage cup lid.
A lid seals through contact between its skirt and the cup rim, so a small difference in rim diameter changes how it behaves. A lid that is too loose can pop off or leak when the cup tips. A lid that is too tight is hard to press on and can crack at the edge. Always test the exact cup and lid together. Fill the cup, press the lid on, invert it briefly over a sink, and then press the dome gently. Run that test with cups from different production lots, since rim dimensions vary a little between lots.
The page says the hole fits standard straws. It does not publish the hole diameter. If you serve pearl milk tea or thick smoothies with wide straws, ask the supplier for the hole size and test it with your own straws. Paper straws that soften quickly or wide boba straws are the usual points of failure.
The manufacturer positions this lid for cold drinks. PET softens at relatively low temperatures compared with polypropylene, so a hot beverage can warp the lid and weaken the seal. Do not use it for hot coffee or tea, and do not leave stacked lids in a hot vehicle or beside a heat source.
Iced drinks form condensation under any clear lid. This is normal and is not a sign of a defect. If clarity matters for display, wipe the dome before handing the drink over.
In the United States, polyethylene terephthalate food-contact articles are regulated under 21 CFR 177.1630 (eCFR text of the regulation). Other markets have their own rules, so ask the supplier for the test reports that apply to your country. The company's certification page lists ISO 9001, ISO 14001, ISO 45001, ISO 22000, BRC A+, GRS and SGS. Those cover its management and production systems, so request the market-specific food-contact documents for this item.
PET is widely recyclable, which the manufacturer notes. In practice, acceptance depends on your local program, since some collectors take bottles and tubs but not lids or thin thermoformed items. Check with your waste hauler before telling customers the lid goes in the recycling bin. If recycled content matters to your brand, look at the RPET series or the PLA series instead.
| Problem | Likely cause | What to try |
|---|---|---|
| Lid pops off | Cup rim and lid skirt mismatch, or an overfilled cup | Test the pair, lower the fill line, send sample cups to the supplier |
| Lid warps | Heat exposure from a hot drink or hot storage | Use for cold drinks only and store in a cool, dry place |
| Straw is hard to insert | Straw wider than the hole | Confirm the hole diameter and switch to a narrower straw |
| Lids stick together | Tight nesting, humidity or static | Keep sleeves sealed until use and fan the stack before loading a dispenser |
| Topping touches the lid | Cup filled too high | Set a fill line that leaves the dome free |
