I'd like to explain the situation.
UCV is our new customer. We noticed that they had bad experience from other suppliers and found many damage product (wet & dirty) and also they don't have clamplift for convenience handling same as us. So they strongly request to us to add some protection to the product (both at the bottom and top of package) at least 1 year until they move to new factory.
Even it cannot protect all contamination but this is just one action to show our willing to support customer.
