>Once my helpers stopped liking, I had expected the viral phenomenon of Facebook to generate more and more likes as the contagion of their likes spread to their friends and colleagues via their own Facebook pages.

You expected your page to go "viral". Your page for packaging products ... to go viral? The people who care about your packaging products are far between on Facebook. The people who care about packaging products will go into google and type "packaging products", or come from your existing referral base, or from leads generated by your sales department. It isn't critical for every business to have a facebook page or a twitter account.
