PaperChef Culinary Parchment Cooking Bags - $3.79 for 10 bags
Quick and easy, these parchment bags eliminate the fussiness of folding and crimping sheets of parchment paper and look better on the plate than a packet of foil does. Simply fill and fold—it’s as easy as stuffing a lunch sack.
The Amazon link below is twice the listed price.
Two were rated as RECOMMENDED:
The traditional French method of folding food en papillote has all the style associated with Paris but takes a lot of work. The packets look great but took more than four times as long to fold as the bags, and crimping and fully sealing the packets required scissors, a ruler, and skill.

Aluminum Foil - $0.10 per use
Folding foil packets is easy and fast: It took a modest 2½ minutes to fill and seal one. But the presentation is poor: Your dinner looks like leftovers before you lift your fork.
