Hi,

I'm looking to get
1. plastic flat 6x12 (width x length) in inches , LDPE , 15 microns
2. plastic tshirts bag 34x17x69 (width x gusset x length) in centimeters , HDPE , 10 microns

I'd like to request samples before any order and know what is the lead time for production and what is the MOQ ?

Thanks.
Maicol
