1. Pre-packaged food
Instant desserts: single cup packaging of refrigerated desserts
such as pudding, jelly, and double skin milk.
Snack packaging: supermarket tasting cups (nuts, candies),
individual small packages in holiday gift boxes (popcorn, potato
chips).
Condiment packaging: small cups of sesame oil and sesame paste in
hot pot restaurants, or mini cups of honey and syrup in retail
stores.
2. Oily foods: Latte coffee and cheese tea containing milk fat are
more resistant to oil penetration than ordinary paper cups.
