selection suggestions: cold drink stores should choose pet cups first, which have high transparency and good display effect; for hot drinks or scenarios that require microwave heating, choose pp cups.Xuchun's pet product line covers four calibers: 90/93/95/98. pp products are mainly injection molded cups with 90 caliber. both can be personalized with logo (view xuchun pet cold drink cup, [view asakatsu pp injection molded cups]https://detail.1688.com/offer/640582482034.html)）。

What are the quality differences between injection molded cups and blister cups?
The craftsmanship directly impacts the uniformity of the cup's thickness, the smoothness of its edges, and the consistency across the entire batch.Understanding the difference between injection molding and blister molding helps you avoid situations where you only discover the quality is off after you've received the goods.
| Comparison dimension | Injection molding process | Blister packaging |
|---|---|---|
| Molding method | Molten plastic is injected into the mold and molded into one piece | After heating, the sheet is adsorbed and formed. |
| Uniformity of wall thickness | Uniform, with high controllable precision. | Bottom and sidewall thickness may vary |
| Edge processing | Smooth, no need for secondary trimming. | May require trimming and edge finishing. |
| Suitable for products | Thick-walled cup, structured lid, functional cup | Thin-walled cup, u-shaped cup, fat cup |
| Mold cost | Higher | Relatively low |
| Flexible minimum order quantity | Usually a certain quantity is required | Small batches are more flexible |
Xuchun is also equipped with injection molding machines and blister machines (factory equipment information comes from the third-party certification page). injection molded products are mainly 90 caliber functional caps and thick-walled cups, and blister products are represented by pet u-shaped cups and fat cups.Buyers can clearly specify the type of craftsmanship they require when inquiring, preventing mixed processes that can lead to inconsistent quality.

How to choose 90, 93, 95, and 98 caliber so as not to waste?
The choice of caliber not only affects the lid fit, but also relates to the type of drink, security of takeaway delivery and purchasing costs.Choosing the wrong diameter can lead to mismatched lids, leaks, or inconsistent brand image.

|---|---|---|---|---|
| 90 mm | 9 oz~16 oz | Standard milk tea, fruit tea | Multi-function cover, arch cover, flat cover | 90 caliber pet cup |
| 93 mm | 9 oz~12 oz | Iced americano, specialty coffee | Dedicated 93 cap | 93 caliber high transparency cup |
| 95 mm | 400ml to 650ml | Large cup of milk tea, fruit tea | 95 arch cover/flat cover | 95 caliber thickened pet cup |
| 98 mm | 12 oz~24 oz | Extra large cup of cold drink, smoothie | 98 series cover | 98 caliber pet cup |

| Comparison dimension | Spot purchase | Customized procurement |
|---|---|---|
| Minimum order quantity | Starting from 1 box (usually 1000 pieces/box) | Starting from 5 boxes (some skus) |
| Proofing cycle | No need to sample | Approximately 3 days (based on xuchun's third-party certification information). |

When comparing prices of the same caliber, which differences really affect purchasing decisions?
When searching for "disposable plastic cups" on 1688, you might find price quotes varying by over 30% for the same diameter and material.The price difference is often due to the following factors:
| Variables affecting price grids | Description | Verification method |
|---|---|---|
| Wall thickness/gram weight | Thicker cups use more material, resulting in a higher unit price. | Request suppliers to provide weight parameters |
| Material grade | New materials vs recycled materials, food grade vs industrial grade | Request a material inspection report. |
| Printing process | Monochrome/multi-color/uv printing costs are different | Confirm the printing method and number of colors |
| The way of packing | Bulk vs. individual packaging vs. carton | Confirm the number of boxes and packaging specifications |
| Minimum order quantity | The unit price is low for large quantities, and the price difference between 1 box and 100 boxes is obvious. | Inquire based on actual demand. |
| Does it include a lid/straw? | Cup + lid + straw set vs single cup | Confirm the accessories included in the quotation |
price comparison tip: don't just look at the price listed in the title. when requesting quotes, be sure to specify the exact specifications (diameter, capacity, wall thickness, material, accessories) so you can accurately compare apples to apples.The xuchun product page clearly indicates the quantity per carton and accessory information (e.g., 98mm diameter 500ml pet cups.https://detail.1688.com/offer/683854591341.html) marked 1,000 pieces/box), can be used as a benchmark reference for price comparison of the same grids.
